Chapter 8, Problem 8.73SP

Interpretation Introduction

Interpretation: The given question stated that when styrene is commercially polymerized, about $1-3\%$ of $1,4-\text{divinylbenzene}$ is often added to the styrene. The incorporation of some divinylbenzene gives a polymer with more strength and better resistance to organic solvents. The explanation for the addition of small amount of divinylbenzene has a marked effect on the properties of the polymer is to be stated.

Concept introduction: Polymerization is a procedure of reacting monomer together during chemical reaction to form polymer chains. There are numerous types of polymerization and distinctive frameworks exist to classify them.

Cross-linked polymers are those in which atom are bonded to polymer chain. They are generally hard and rigid in nature.

To determine: The explanation for the addition of small amount of divinylbenzene has a marked effect on the properties of the polymer.
