Imagine losing half of your closet, and half of your collections.
It'd be half the world you're currently in, because many things in the world are made of polymers.
Starch, proteins (e.g. wool and silk), DNA, cellulose (cotton), spider web.
Examples: starch, cellulose, polypeptides, nucleic acids.
Starch, Cellulose, Proteins......
Melt spinning is used for polymers that can be melted i.e. the polymers must have a melting temperature (thermoplastic polymers). Dry spinning is used for polymers that do no have melting temperature and need to be dissolved in solvent (thermoset polymers). In case of melt spinning, the polymer solidifies by cooling after being extruded from the spinneret. Whereas, in case of dry spinning, the polymer solidifies through evaporation of solvents and this is achieved by a stream of air or inert gas.
form polymers from monomers
These are used in making polymers, plastics and lubricants.
Something with a low coefficient of friction such as PVC or PTFE polymers
socks, dough, clay, bed sheet and rubber band
Nature polymers and synthetic polymers are both large molecules made up of repeating units called monomers. They both have high molecular weights and exhibit similar properties like flexibility, strength, and durability. Additionally, both nature and synthetic polymers can be engineered to have specific properties for various applications.
There are several polymers in living beings, for example, proteins, DNA, RNA, and polysaccharides.
Examples: starch, cellulose, polypeptides, nucleic acids.
Rubber is a natural polymers with elastic and plastic type behavior. It is found in nature and extracted from trees. PET (soda bottles) Polyethylene Terephthalate is a synthetic polymer and not found in nature.
Teflon is a synthetic polymer which means that it is man-made. There are many polymers that are also found in nature.
A natural polymer would be rubber which is obtained from nature. A synthetic polymer would be polybutadiene which behaves like rubber.
Polymers are used all around, plastics and rubber are polymers.
Natural polymers will degrade over time.... man-made polymers are not biodegradable - and need to be processed.
Water soluble polymers are polymers that will dissolve in water.
they are called polymers
modified natural polymers are natural polymers which are altered in order to suit a particular purposeModified natural polymers are natural polymers which are altered in order to suit a particular purpose. Modified natural polymers are natural polymers which are altered in order to suit a particular purpose.
The polymers of carbohydrates are polysaccharide.
