Chapter 26, Problem 26.41P

Interpretation Introduction

(a)

Interpretation:

A mechanism for the initiation step for the polymerization reaction in Problem $\text{26}\text{.40}$ is to be determined.

Concept introduction:

Polymerization is a process of reacting monomer molecules together in a chemical reaction to form polymer chains or three-dimensional networks. This are classified by different syatem avaible for the different types if polymerization.

The polymerizations can be initiated by anions or cations, resulting in anionic polymerization or cationic polymerization, respectively. The polymerization involves, 1) initiation, 2) propagation, and 3) termination.

Initiation is the first step of the polymerization process. An active center is created during initiation, from which a polymer chain is generated. Not all monomers are susceptible to all types of initiators.

In propogation a reactive intermediate is repetitively redeveloped throughout the sequence of a chemical chain reaction. Then it is terminated by adding mono functional groups that having equal of different types of monomer.

Interpretation Introduction

(b)

Interpretation:

A mechanism for the first two propagation steps for the polymerization reaction in Problem $\text{26}\text{.40}$ is to be determined.

Concept introduction:

The chemical reaction in which the monomer molecules reacts together to form polymer chains or three dimentional networks is termed as polymerization. This are classified by different syatem avaible for the different types if polymerization.
