The structures of the given copolymer are to be drawn. Concept introduction: Copolymer is defined as polymers whose repeating structural units are derived from two or more types of monomer units. Polyesters are polymers of an acid, benzene-1, 4-dicarboxylic acid ( terephthalic acid ) and an alcohol, ethane-1,2- diol . It is also known as polyethylene terephthalate ( PET ) . Polyesters are formed by condensation polymerization reactions in which the individual units are held by ester linkages between monomers, which involve the carboxyl and hydroxyl functional groups.

Solution Summary: The author defines copolymer as polymers whose repeating structural units are derived from two or more types of monomer units.
Definition Definition Monomer units that are initially formed as a linear polymer, before polymer chains join to form a three-dimensional network structure. They are hard, rigid, and brittle. The molecular weight of a cross-linked polymer is very high. Examples of cross-linked polymers are Bakelite and urea-formaldehyde polymer.

Interpretation Introduction
Interpretation: The structures of the given copolymer are to be drawn.
Concept introduction: Copolymer is defined as polymers whose repeating structural units are derived from two or more types of monomer units. Polyesters are polymers of an acid, benzene-1, 4-dicarboxylic acid
(terephthalicacid) and an alcohol,
ethane-1,2-diol. It is also known as
polyethyleneterephthalate(PET). Polyesters are formed by condensation polymerization reactions in which the individual units are held by ester linkages between monomers, which involve the carboxyl and hydroxyl functional groups.
