(a)

Interpretation Introduction

Interpretation:

The type of the polymer of compound poly $\left(\text{butylene}\text{terephthalate}\right)$ is to be predicted.

Concept introduction:

Polyesters are the polymers that consist of ester functional group in the main polymer chain. Polyesters are formed by the condensation polymerization reaction.

(b)

Interpretation Introduction

Interpretation:

The compound poly $\left(\text{butylene}\text{terephthalate}\right)$ is an addition polymer or a condensation polymer is to be predicted.

Concept introduction:

Polymerisation is the process in which the small molecules that are monomer molecules link together in a chemical reaction to form large chain that are called polymer.

An addition polymer is the polymer that is formed by the simple addition of the monomer without the removal of other products like water or methanol. It is chain-growth polymerization process.

Condensation polymerisation is the process for the formation of polymers in which the polymers are formed by the linkage of the molecule with removal of small molecules like water or methanol. It is a step-growth polymerization process. The compound formed by condensation polymerisation is a condensation polymer.

(c)

Interpretation Introduction

Interpretation:

The monomers of the compound poly $\left(\text{butylene}\text{terephthalate}\right)$ are to be predicted and the polymerisation that is accomplished in the formation of poly $\left(\text{butylene}\text{terephthalate}\right)$ is to be elaborated.

Concept introduction:

Polymerisation is the process in which the small molecules that are monomer molecules link together in a chemical reaction to form large chain that are called polymer.

The repeating unit that link to form large chain polymer are called monomer.
