Q. 21

(i) Identif

Answer :

(i)


The monomer of the given polymer can be determined from the given polymeric structure and is CH2-CH=CH-CH2-CH2-CHCN.


(ii)


On the basis of forces between molecules of a polymer neoprene being a member of the synthetic rubber family can be classified as elastomer as in this type of polymers the polymeric chains are held together by weak intermolecular forces.



(iii)


Copolymerisation is a polymerisation reaction in which a mixture of more than one monomeric units are allowed to polymerise and form a copolymer.


The copolymer can be made not only by addition polymerisation(chain growth polymerisation) but also by condensation polymerisation (step growth polymerisation) also.


Hence both addition and condensation polymerization can give result to the formation of a copolymer.
