Question

Which of the following is a condensation polymer?
A. Teflon
B. PVC
C. Polyester
D. Neoprene

Answer 1

Hint: It is synthetic fiber derived from coal, air, water and petroleum. It is formed from a chemical reaction between an acid and alcohol.

Complete step by step answer:
Let us first understand what a polymer is:
In simple words polymers are materials made of long repeating chains of molecules. The materials have unique properties, depending on the type of molecules being bonded. Some polymers bend and stretch, like rubber and polyester others are hard, tough, like epoxies and glass.

Let us understand what a condensation polymer is.
Condensation polymers are nothing but the polymers which are formed by condensation reaction.
In this reaction we can observe that the molecules are joined together by losing small molecules as byproducts such as water or methanol.
Condensation polymers are formed by polycondensation.
The main alternative forms of polymerization are chain polymerization and polyaddition, both of which give additional polymer.

Now, let us consider the question.
Polyester is a condensation polymer; It is a synthetic fabric that’s usually derived from petroleum. Chemically, polyester is a polymer primarily composed of compounds within the ester functional group.
Most of the synthetic polyesters are made from ethylene, which is a constituent of petroleum that can also be derived from other sources.
It is made of purified terephthalic acid (PTA) or dimethyl terephthalate (DMT) and a monoethylene glycol (MEG).
Some forms of polyesters are biodegradable but most of them are non-biodegradable.

Hence, Polyester is a condensation polymer. Therefore, option A is the required answer.

Note: You should know that production of polyester uses harmful chemicals, including carcinogens and if these chemicals are emitted to water and air, can cause significant environmental damage.
