Question

Quizplus · Accepted Answer

Polycarbonates are formed by step growth condensation polymerization, in which a monomer with two or more reactive groups, such as bisphenol A, reacts with a diacid chloride to form a polymer chain through the elimination of small molecules, such as HCl. This process involves the coupling of two different functional groups to form a new bond, rather than the repetitive addition of monomers in chain growth polymerization.
