POLYMERS :-
DESCRIPTION:
Polymer is a term used to describe molecules
consisting of structural units and a large number of
repeating units connected by covalent chemical bonds.
The term is derived from the Greek words: polys meaning
many, and meros meaning pars.
The key feature that distinguishes polymers
from other molecules is the repetition of many identical,
similar, or complementary molecular subunits in these
chains. These subunits, the monomers, are small molecules
of low to moderate molecular weight, and are linked
to each other during a chemical reaction called polymerization.
