Question

Definition Definition Chemical process in which one or more monomers combine to produce a very large chain-like molecule called a polymer. The functional groups present on the monomers and their steric effects are responsible for polymerization through a sequence of reactions that vary in complexity. There exists a stable covalent chemical bond between monomers that sets apart polymerization from other processes.

Chapter 22, Problem 55A

Interpretation Introduction

Interpretation:

The type of polymer which is easier to recycle needs to be determined.

Concept introduction:

The monomer units combined together to form polymer in the polymerization reaction. There are two types: addition and condensation polymerization.

Expert Solution & Answer

Explanation of Solution

There are two types of polymers namely thermosetting and thermoplastics.

Thermoplastic polymers become soft on heating but thermosetting polymers does not become soft on heating.

Thermoplastic polymers have long linear chain and they are formed by addition polymerization. On the other hand, thermosetting polymers have 3D structure and they are formed by condensation polymerization reaction.

Thermoplastics can be reshaped and reuse because they are soft weak and less brittle but, thermosetting polymers cannot be reshaped due to their hard and strong nature.

Thermoplastics are soluble in organic solvent but thermosetting polymers are insoluble in organic solvents.

The thermoplastics are formed by monomer units which are covalently bonded and they have weak van der Waal of interactions between them. On the other hand, thermosetting polymers have strong cross-links and 3D network of atoms which are covalently bonded.

Thus from the above properties of thermoplastics and thermosetting polymers, thermoplastics can be easily recycled.
