The correct name of the following polymer is:

Options

APolyisobutylene
BPolytert-butylene
CPolyisobutane
DPolyisoprene

Correct answer

A. Polyisobutylene

Step-by-step solution

Polyisobutylene is a polymer molecule which is produced by the polymerization of isobutene (also known as 2-methylpropene). The chemical formula of isobutene is ( CH 3 ) 2 C = CH 2 . Polymerization happens according to the following reaction:
