(a) What is meant by polymerisation? Name the monomer used in the preparation of Polyvinyl Chloride (PVC).
(b) Write partial structure of the following polymers.
(i) Poly propene
(ii) Teflon
(iii) Neoprene

Explanation

The process of formation of polymers from the respective monomers is called polymerisation. (b) (i) Poly propene.
`[-CH_(2)-overset(CH_(3))overset(|)(C)H]_(n)`
(ii) Teflon `[CF_(2)-CF_(2)-]_(n)`
(iii) Neoprene `[-CH_(2)-overset(Cl)overset(|)(C)=CH-CH_(2)-]`.
