Chapter 21, Problem 79E

Interpretation Introduction

Interpretation: The rigidity of copolymer by $\text{divinylbenzene}$ is to be stated.

Concept introduction: Copolymers are defined as polymers whose repeating structural units are derived from two or more types of monomers unit. Polystyrene is a polymer made from the monomer styrene. This polymer can be made more rigid by copolymerizing styrene with $\text{divinylbenzene}$. Copolymerization reactions are those polymerization reaction in which two or more types of monomer units react together to form the final polymer.

To determine: The more rigidity of copolymer by $\text{divinylbenzene}$.
