Distinguish the two polymerization routes and connect them with poly(ethene), PVC, polyesters, and polyamides.
Describe the chemical processes of addition and condensation polymerization and the differences between them. Examples include, a. addition polymers such as poly(ethene) and poly(chloroethene), PVC, b. polyesters (from reactions of diol and dicarboxylic or dioyl acid, and from hydroxycarboxylic acid), c. polyamides (from reactions of a diamine and a dicarboxylic acid or dioylchloride, of an amino carboxylic acid, or between amino acids).
