Plastics and Polymers

Parent Category: Chemistry
The category should be plastics and polymers. We have a category of metals under chemistry. Plastics and polymers are the fasting growing category of materials. A Styrofoam cup is a plastic or polymer for example.

Polymers consisting of chains of monosaccharides are calledpolysaccharides.
it depends on what closet like clothe closet is made out ofwood
If you add pva glue (or mod Podge) to the paint first or if youpaint a couple of layers of it over the paint it shouldn't scratch.
Pretty much every method of producing plastic has non-poisonousproducts. Polymerising alkenes under pressure and polyesterformation are the two main ways of producing plastic, and neitherhave toxic products.
Yes. Yes it is.
Some advantages of buying plastic packaging are: Plastic is flexible Transportation and storing plastic is easy and safe Plastic takes up less energy to recycle Some advantages and disadvantages of buying plastic packaging are: Plastic debris poses a huge threat to our ecosystem, filling up...
toys, keys on a keyboard, water bottles, legos, and light switches.
When a shape memory polymer is used to stitch a wound loosely, the temperature of the body makes the thread tighten and close the wound, applying just the right amount of force. This is an example of a 'smart' polymer. i.e. one that changes in response to changes around it. In this case a change in...
Proteins are polymers!! Long chains of amino acids....
The elasticity of a polymer depends on the cross-linking of its chains.
They're not. They're usually copper or aluminium, which are metal !
A polymer is a large molecule composed of repeating structural units typically connected by covalent chemical bonds. Some examples are as follows . Plastics . DNA . rubbers
Starch, proteins (e.g. wool and silk), DNA, cellulose (cotton), spider web.
They are made all over the world.
it is measure of carboxylic end groups of polymers
They are myriad. Plastics are made from petroleum and can leach allkinds of toxins that are released by either heat or cold. Plasticwater bottles specifically can leach something calledphyto-estrogen, which can distrupt the reproductive organs in fetusand small children. Plastics left unattended in...
Essentially, a polymer is any substance whose molecules are madefrom very large numbers of identical repeating units. "Plastic" isa generic term often used to describe polymers that have "plastic"properties (i.e. they are able to be moulded, shaped or formedrelatively easily).
It's real important to apply your Teflon tape in a clockwisedirection which coincidentally is the same way you thread on mostof your fittings.. If you apply the tape in an anticlockwisedirection it will unravel as you screw on the fitting which willrender it useless. To apply , this is what l find...
Polysaccharides are polymers of monosaccharides, which are carbohydrates. Starch and cellulose are made from glucose. Other polysaccharides are made from mannose, glacturonic acid, galactose, and fructose.
No plastic is not an element because if you look at the periodic table, it is not mentioned.
Macromolecules are linked with covalent bonds between its monomers. For example proteins are bonded with peptide bonds. Hydrolysis of these bonds will break them to small peptides and ultimately forms amino acids. For any other macromolecules the same hydrolysis is a key to separate them. This...
They're called polysaccharides and they exhibit a great diversity of form and composition. Examples include amylopectin and amylose found as starch in plants and glycogen found in animals all used for secondary energy storage. Together with cellulose, which is also a polysaccharide, these are the...
yes polymerization yields them. amino acids polymerize to form proteins by peptide bond. Simple sugars such as glucose make glycogen or starch.
Many people do, so it's quite safe. However we should all try toreduce our usage of disposable plastic so re-usable boxes would bebetter.
Well that is a dumb qwestion they are made out of plastic.
It is wise not to store cooked food in a teflon pot in the fridge. Use plastic or glass pot to sore food in the fridge, not cooking pot.
They end up in landfills and degrade over tens of years. They also have to be transported to the store by huge trucks, which emit CO2. Using a reusable bag helps the Earth for only 99 cents! In many states laws are bing passed; you get fined 5 cents per plastic bag! :) Animals also think of it as...
Teflon didn't actually replace anything. It was developed for the space program to reduce friction and then someone got the idea to use it on cooking items to prevent sticking.
This reaction is called polymerization; see the link below.
DNA consists of two long polymers of simple units called nucleotides , with backbones made of sugars and phosphate groups joined by ester bonds. These two strands run in opposite directions to each other and are therefore anti-parallel. Attached to each sugar is one of four types of molecules...
Polyacrylonitrile, Acrylonitrile butadiene styrene
Teflon weighs approximately .079 LBS per cubic inch.
Ethylene Propylene
Cholesterol is a big molecule, C 27 H 46 O. However, it is a single molecule, and thus a monomer. In cells cholesterol is normally embedded in cell membrane and makes hydrogen bonds with surrounding molecules. In the blood, it is also not found alone, but packaged with lipids (triglycerides...
Teflon is a trade name for PolyTetraFluoroEthylene -PTFE. It is made by polymerization of Tetra Fluoro Ethylene CF 2 =CF 2 and thus because it is a synthetic polymer it is generically called a plastic and in addition it has properties of a plastic.
DNA and RNA are polymers of nucleotides. DNA is made up of deoxy ribose sugar and RNA contain oxy ribose sugar. Both DNA and RNA are made up of nitrogenous bases provided by their nucleotides. In RNA Thymine is replaced as Uracil.
science people to make expirements and diffrent things with that
This is due to the cross linking in the Polymers, (Rocket stop cheating)
Polycarbonate/Acrylonitrile Butadiene Styrene (PC/ABS) - A blend of PC and ABS that creates a stronger plastic. Used in car interior and exterior parts, and mobile phone bodies.
Nucleic acids are polymers made from chains nucleotide monomers.The most well known of which are DNA (deoxyribonucleic acid) andRNA (ribonucleic acid).
People and animals can choke on them and they take up space in landfills for a long time if discarded rather then recycled.
Answer . I do not know of any polymers that are 100 percent crystalline. This is because most of the polymers you can make or buy have different molecular weights. So unlike small molecules, there are some differences in sizes between polymers. These differences prevent the polymer from being...
PTFE stands for polytetrafluoroethylene. Teflon is the registered trade mark for this, and is owned by DuPont.
synthetic polymers play a vital role in our life.. for eg., the materials used in day-today life like buckets, switches,dresses etc
Carbohydrates are the molecules made of sugar repeats. Starch, cellulose and glycogen are classical example for the same. They can be digested back to the monomers by the enzymes that catalyse the hydrolysis reaction such as cellulase or amylase.
\nYep - it's made from crude oil products.
It can be used in the place where we need the permanancy in our information....it is very useful in networking field through this we could protect the ip address hackers........we can use this even there is no power..........
There are thousands of compounds that react with plastic. However,acids are the strongest reactors. Sulfuric acid eats away plasticvery quickly.
Water soluble polymers are polymers that will dissolve in water.
He was a crook in a chemical plant, and a guard shot his arm and he was covered in acid. Then he became a hero fighting for justice.
Paper bags are a very good alternate for Plastic bags because: They are bio-degradable and do not cause environmental pollution. The main reason why people do not go for Paper bags is because, plastic bags are cheaper than paper bags. If we as customers insist with shopkeepers that we would not...
Here are some nice promotional products made out of plastic -http://www.plasticproductsmfg.com/Browse-Catalog/acrylic-sign-holders/
high molecular poly bags
Because plastic is a non-conductor and as such does not conductelectricity.
"Polymerization" comes in the booster packs: . Legend of Blue Eyes White Dragon . Dark Beginnings 1 . Starter Deck Joey (not a booster pack, but it does have the card) . GX Jaden Yuki . Retro Pack One . Dark Legends . Duelist Pack Yugi
No. Only conductiong materials.
They clean etremely easily, all you generally need is warm water and a little bit of soap and a wipe and a rinse.. with liquid dishsoap, hot water and a PLASTIC brush or sponge (never use steel wool or metal cause you will scratch it and ruin it)
Amino acids form proteins.
you can easily find empty plastic film canisters from online shops. if for some reason you can buy online(like me), then i really haven't seen any in a long time. but I'm searching as well, and will update as soon as i find them.
polymers: as the worm spell poly:means many and mer: means unit. These molecule have hibh molecular mass. They are formed of monomers joined by covalent bonds. Process called polymerization.
Here are some of the harmful effects of plastic bags: Plastic bags litter the landscape. Once they are used, most plastic bags go into landfill, or rubbish tips. Each year more and more plastic bags are ending up littering the environment. Once they become litter, plastic bags find their way...
You have to put them in a cabinet and maybe if you go to save alot and get those bags so u wont pay extra. and you might want to go and just pick up your animals' mess
Answer . One time I used a sheet of paper and an iron. Lay the sheet of paper over it and take a hot iron and put over the paper. It will melt the plastic and it will stick to the paper.. Answer . I am not sure about melted plastic, but I've removed dried wax from fabric by placing a brown paper...
