What do you mean by synthetic polymers?

There are natural and synthetic polymers .Cellulose, natural rubber ,starch,proteins etc come under natural polymers. The man-made polymers are called synthetic polymers like PVC,Polyethylene, Teflon.
Polymers are high molecular weight compounds and are made of simple repeating units of low molecular weight compounds.These simple compounds are called monomers. In short, polymers are made of several monomers. And for this the reaction we do is polymerisation reaction.Some polymers are given below.
(1) polyethylene . It is made by polymerization of ethylene .Here, the monomers used is ethylene.
(2) Teflon.  It is made by polymerisation of tetrafluoroethylene.
(3) Polyvinyl Chloride.  It is prepared by polymerising vinyl chloride.
 (4)Polypropylene.  It is obtained by polymerising propylene.
There are large number of polymers.
