Question

During emulsion polymerisation particle size decreases.

(a) True

(b) False

This question was addressed to me during an online interview.

This interesting question is from Methods of Polymerization topic in section Principles of Polymer Chemistry of Unit Processes

Answer 1

Correct option is (a) True

To explain: During emulsion polymerization under the influence of heat and appropriate catalysts, the average particle size decreases to about one-tenth of its starting size, and the polymer is usually obtained in the form of a very stable emulsion called a latex.
