REACTION POLYMER
Definition
A <REACTION POLYMER> is a <POLYMER> that is produced by step-reaction (condensation) polymerization; this proces typically produces polymers of lower molecular weight than chain reactions and requires higher temperatures to occur. Unlike addition polymerization, step-wise reactions involve two different types of di-functional monomers or end groups that react with one another, forming a chain. Condensation polymerization also produces a small molecular by-product (water, HCl, etc.)
