Question

Which of the following sets contain only copolymers?

• A. SBR, Glyptal, Nylon - 6, 6
• B. Nylon - 6, Butyl rubber, Neoprene
• C. Polythene, Polyester, PVC
• D. Melmac, Bakelite, Teflon

Answer 1

The correct option is A

SBR, Glyptal, Nylon - 6, 6

SBR, Glyptal, PMMA can be classified under copolymers. Do you think copolymers and condensation polymers are the same? No, they are not.

There is a small difference between them.

Although both are made from more than one monomer units, in the case of condensation polymers a water molecule is released when the polymer is formed.

And in the case of copolymers, there is no release of any molecules. The monomer units just join together in a long chain.
