Organic Chemistry III
Amides and condensation polymers
- 3 things to know
- Papers 2 and 3
Overview
Acyl chlorides forming amides, condensation polymerisation to polyesters from dicarboxylic acids and diols and to polyamides from dicarboxylic acids and diamines, their ester and amide linkages, and the water eliminated as each linkage forms.
