Question

The formation of a condensation polymer generally involves ________. the elimination of a small molecule the addition of a plasticizer the vaporization of a plasticizer the mixing of sulfur with an addition polymer the formation of significant crosslinking

Answer 1

Condensation polymers are made by removing a small molecule from the ends of the monomer (for example, water in nylon polymerization), allowing the main part of the monomer to combine with the rest. The first choice is the correct answer.

Plasticizers do not polymerize, but they change mechanical properties. The addition of sulfur and crosslinks are mainly for rubber in vulcanization, but not so much for condensation polymers.
