Generally:
- they have a low thermal and electrical conductivity;
- their deformation is very temperature dependent;
- low Young module (they deform a lot for low tensions/strenghts);
- the atoms are bond by covalent and secondary bonds (Van der Walls
and hydrogen bonds)

What is acrylic polymer?
Acrylic polymers are compounds produced by bonding acrylic acid or acrylic ester with other molecules. Acrylic polymers utilize the desirable characteristics of acrylic acid and acrylic ester and are used in dispersants, thickeners, adhesives, binders, and paint vehicles.
What is the definition of semi -synthetic polymer?
semi-synthetic polymers are obtained from natural polymers by subjecting them to some chemical processes. eg: vulcanised rubber.
Why are some polymers stretchy while others are not?
There are some polymers which are stretchy while the others are not because of the disordered structure. Elasticity refers to the ability of a polymer to stretch past its original length.
Why do natural polymers not pose as much of an issue in landfills as synthetic polymers Natural polymers are cheap to recycle and synthetic polymers are expensive to recycle. Natural polymers are expe?
Natural polymers will degrade over time.... man-made polymers are not biodegradable - and need to be processed.
Do polymers have double bonds?
Yes. Some polymers have double bonds, for example natural rubber - poly isoprene . See link for structure. However many polymers that are familiar do not polyethylene is (C2H4)n , polyvinyl chloride (C2H3Cl)n
How do you alter characteristics of polymers?
Characteristics of polymers can be altered by: irradiation, treatment with oxygen or other chemicals, rising the temperature, using additives in the composition.
What are the uses of polymers to mankind?
Plastics, which are polymers plus some additives, are their main use.
What are example of Some polymers?
Molecules
Do Polymers come from plants?
Plants do make and use some polymers (e.g. starch, cellulose etc.), as do some animals (e.g. spider silk) but most of what we know as polymers are artificial (e.g. polyethylene, nylon etc.).
What is acrylic polymer?
Acrylic polymers are compounds produced by bonding acrylic acid or acrylic ester with other molecules. Acrylic polymers utilize the desirable characteristics of acrylic acid and acrylic ester and are used in dispersants, thickeners, adhesives, binders, and paint vehicles.
Name some polymers that are produced in nature?
There are several polymers in living beings, for example, proteins, DNA, RNA, and polysaccharides.
What is the difference between organic polymers and inorganic polymers?
In general organic contains carbon molecules and/or those related to life. It is the chemistry of carbon containing compounds.Inorganic is everything else and generally do not contain carbon (with some exceptions).
What are some macromolocules?
Macromolecules are polymers. There are bio-polymers such as carbohydrates, proteins, lipids and DNA, and there are synthetic polymers such as plastics (polystyrene and polyvinylchloride) and synthetic fibres. Nylon and terylene are also considered macromolecules.
Which element contains organic polymers?
Elements do not contain polymers. It is the other way around. Organic polymers contain elements. These are usually C, O, H, N, Halogens and some others.
What is the definition of semi -synthetic polymer?
semi-synthetic polymers are obtained from natural polymers by subjecting them to some chemical processes. eg: vulcanised rubber.
Some polymers are elastic because they are made up of?
Protein.
Why are some polymers stretchy while others are not?
There are some polymers which are stretchy while the others are not because of the disordered structure. Elasticity refers to the ability of a polymer to stretch past its original length.
