(i) `[-CH_(2)-overset(CH_(3))overset(|)(C)H-]_(n)` a homopolymer or copolymer ? Give reason.
(ii) which the monomers of the following polymer.
(iii) What is the role of Sulphur in vulcanization of rubber?

Text Solution

Verified by Experts

`[-CH_(2)-overset(CH_3)overset(|)(CH)-]_(n)` is a homopolymer because it is polymerised by single monomer.
(iii) See Q.20 (i) Paper 2016, Outside Delhi, Set-I, [Page 359].
