Question

What is a copolymer?

• A. A polymer formed from condensation polymerization
• B. A polymer made of 2 or more monomeric units
• C. A polymer with exactly 3 monomeric units.
• D. A condensation polymer of similar monomeric units

Answer 1

The correct option is B A polymer made of 2 or more monomeric units

A copolymer is a polymer made with 2 or more monomeric units. The polymer with only 1 type of monomeric unit is called a homopolymer.

An example of a copolymer is nylon-6,6 which is made of hexamethylene diamine and adipic acid. But let's not get confused between a condensation polymer and a copolymer.

The name condensation polymer is based on the process of the formation of the polymer whereas copolymer just indicates that there are 2 or more monomeric units. It's possible to have an addition polymer which is a co-polymer.
