Which of the following statements correctly describe the step-reaction polymerization?
I.It is also called condensation polymerization.
II.It produces polymers of moderately high molecular masses.
III.It requires that monomers have functional groups that can join together.
IV.This type of polymerization is fast.
V.It is accompanied with the addition of a small molecule.

Question

Quizplus · Accepted Answer

Statement I is correct, as step-reaction polymerization is also known as condensation polymerization. Statement II is also correct, as step-reaction polymerization produces polymers of moderately high molecular masses. Statement III is correct, as this type of polymerization requires monomers that have functional groups that can join together. Statements IV and V are incorrect, as step-reaction polymerization is a slow process and can result in the elimination of small molecules rather than their addition. Therefore, the best choice is A, as it includes all the correct statements.
