What are the differences between polyamide and polyimide?

Question

Accepted Answer

The differences between polyamide and polyimide are listed in the table below.

Polyamide
Polyimide

Is a synthetic polymer made by the linkage of an amino group of one molecule, and a carboxylic acid group of another molecule
Is a very strong polymer made from imide monomers

Has recurring amide linkages
Has recurring imide linkages

Its monomers are diamines and dicarboxylic acids 
Its monomers are either dianhydride and diisocyanate or dianhydride and diamine

Examples are nylon, Kevlar (synthetic polyamides) and wool and silk (natural polyamides) 
Examples are Kapton, Apical, and Kaptrex
