Answer
This is an example of a copolymer.
It is formed by condensation polymerization.
The monomers for this polymer are:
a) terephthalic acid and b) ethylene glycol. Structures of these compounds are written below.
Work Step by Step
This is a copolymer because two monomers are bonded together by condensation reaction and then polymerizes to form this polymer.
It is formed by condensation polymer because two monomers bonded together by eliminating one OH group from -COOH group of terephthalic acid and eliminating one H atom from OH group of ethylene glycol to form the dimer and then the dimer polymerizes to form the polymer.
See below figure.
