Question

Match the polymers given in Column I with their chemical names given in Column II.

	Column I		Column II
(i)	Nylon 6	(a)	Polyvinyl chloride
(ii)	PVC	(b)	Polyacrylonitrile
(iii)	Acrilan	(c)	Polycaprolactam
(iv)	Natural rubber	(d)	Low density Polythene
(v)	LDP	(e)	$cis-$ Polyisoprene

Answer 1

Part(i):

Nylon 6 – It is obtained by heating caprolactam with water at a high temperature. Hence, Nylon 6 is also called polycaprolactam.

(i)

Nylon 6

(c)

Polycaprolactam

Part(ii):

$PVC-$ Polyvinyl chloride is a polymer of vinyl chloride $(C{H}_2=CHCl)$.

(ii)

PVC

(a)

Polyvinyl chloride

Part(iii):

Acrilan - It is an addition polymer of acrylonitrile in the presence of a peroxide catalyst.

(iii)

Acrilan

(b)

Polyacrylonitrile

Part(iv):

Natural rubber - It is a linear polymer of isoprene (2-methyl-1,3-butadiene) and is also called $cis$- 1,4-polyisoprene.

(iv)

Natural Rubber

(e)

$cis$-Polyisoprene

Part(v):

LDP – Low-density polythene is obtained by the polymerisation of ethene in the presence of traces of dioxygen or a peroxide initiator (catalyst).

(v)

LDP

(d)

Low density polythene
