Question

Which of the following options is/are true about the polymer terylene?

• A. It is a co-polymer
• B. It is a condensation polymer
• C. It is a polyester
• D. Its monomers are ethane-1,2-diol and phthalic acid

Answer 1

Answer: (A), (B), (C)

The correct options are
A It is a co-polymer
B It is a condensation polymer
C It is a polyester

a) Copolymers are those which are formed from two or more different monomers. The monomers of terylene are terephthalic acid and ethylene glycol. So, it is a copolymer.
b) It is a condensation polymer as during polymerization, water molecules is removed.
c) Polyesters are a class of polymers which contain ester groups in their main chain. So, terylene is a polyester.
d) The monomers of terylene are terephthalic acid and ethane-1,2-diol.
