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
Name some natural river?
Such a river would be still in the form as it was produced exclusively by nature. Now days it would be impossible to find a river without any form of interference from man.
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 acid produced by plant roots?
Auxins is the name of the acid produced by some plant roots.
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.
Is plastic a solid crystalline?
Some plastics are, some are not. Polymers like polyethylene and polypropylene can be partially crystalline. Typical commercial polystyrene is not crystalline, although a crystallized resin form (syndiotactic polystyrene) has been produced that resists deformation up to about 270 degrees C.
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.
