Step-growth polymerisation (1): The formation of polyamide

Principle
Adipic acid and hexamethylene diamine react with each other to form a polymer. In this reaction, water is splitt off when the dimer is formed. The resulting dimer is capable of polymer formation due to the still present functional groups. This type of reaction is called step-growth polymerization (condensation polymerization). A reaction of adipic acid by adding hexamethylene diamine is produced in this experiment.
