Chapter 27: Q35P (page 1210)

Five different repeating units are found in the polymer obtained by cationic polymerisation of 4- methyl-1-pentene. Identify these repeating units.

Short Answer

Expert verified

The answer is,

Addition of carbocations

Step by step solution

01

Cationic polymerization

The polymerisation occurs by forming cation intermediates known as cationic polymerisation. This is a type of polymerisation in which a cation undergoes initiation of the polymerisation reaction by transferring the monomers to the growing end.

02

Explanation

The carbocations undergo the addition to the growing end of the polymer chain.

The five carbocations and addition are shown below.
