Question

What is the rate of growth of chains in condensation polymerization?

(a) 10^-2 to 10^2 seconds

(b) 10 minutes

(c) Hours or days

(d) Weeks

The question was posed to me by my college director while I was bunking the class.

This is a very interesting question from Polymers and Polymerization, Polymer Additives topic in division Non Metallic Materials of Engineering Material & Metallurgy

Answer 1

The correct answer is (c) Hours or days

Explanation: Condensation polymerization results in the production of tri-functional monomers. These generally take a larger time for condensation; say a few hours to a few days. Addition polymerization takes 10^-2 to 10^2 seconds for chain growth.
