Abstract

Polyhydroxyamides are polymerized to form highly-crosslinked, temperature-stable polymers. The polyhydroxyamides include as their central, parent structure a benzenetricarboxylic acid to which side chains containing a terminal reactive group are attached by an amide bond. By way of this reactive group, highly crosslinked polymers can be formed. In addition, the polyhydroxyamide can be added as an additive to polymers in order to bring about three-dimensional crosslinking.
