name any three polymers and their monomers
Answers
Answer:
The process of formation of molecules of polymers bye the combination of small unit molecules, is called polymerisation
Polymers are large molecules, consisting of a large number of small units called monomers e.g. when Ethylene is heated at high temperature and high pressure, its molecules unite together to form a high molecular weight compound called Polythene. This process is called Polymerisation.

where n is the number of molecules.
In the same way, Polyvinyl Chloride (P.V.C.), Teflon, Neoprin etc. are also polymers.
Some important polymers, their method of preparation, properties and uses -
1. Polythese (Poly + Ethene = Polythene) It is a synthetic polymer of the additional series.
It's monomer unit is ethylene.

Property - It is transparent, elastic, strong, and solid plastic.
use - It is used in making raincoats, toys, pipes, bags etc.
2.Polyvinyl Chloride (P.V.C.) - It is also synthetic polymer of additional series. It's monomer unit is Vinyl chloride.
