Question

Which one of the following polymers is prepared by condensation polymerization?

• A. Teflon
• B. Nylon-6,6
• C. Rubber
• D. Styrene

Answer 1

The correct option is B

Nylon-6,6

The correct option is B.

Explanation of the correct option:

1. Condensation polymerization refers to the process of formation of larger molecules; from small molecules or monomers reacting with each other.
2. Examples are Nylon, Bakelite, etc.
3. Nylon-6,6 is a polymer of Hexamethylenediamine and adipic acid.

Explanation of the incorrect options:

Option A:

1. Teflon is chemically inert, used to make acid-base carrying a content coating of utensils.
2. The formation process of Teflon is Vinyl polymerization.

Option C:

1. Rubber is natural rubber, a linear polymer of cis-1,4 polyisoprene.
2. The formation process of rubber is radical chain polymerization.

Option D:

1. Styrene is an organic compound, used to make latex, and synthetic rubber compounds.
2. It evaporates easily and has a sweet smell.
3. The formation process of styrene is self-polymerization.

Final answer: Nylon-6,6 is prepared by condensation polymerization.
