Process for the production of copolyamide from aromatic dicarboxylic acids, adipic acid and hexamethylene diamine

A process for the production of copolyamides from aromatic dicarboxylic acids, adipic acid, and hexamethylene diamine having from 30 to 51.5% by weight of units of the hexamethylene adipic acid amide, the monomers being precondensed at at least 250 DEG C. and under a pressure of at least 35 bars and...

Zusammenfassung:	A process for the production of copolyamides from aromatic dicarboxylic acids, adipic acid, and hexamethylene diamine having from 30 to 51.5% by weight of units of the hexamethylene adipic acid amide, the monomers being precondensed at at least 250 DEG C. and under a pressure of at least 35 bars and the polycondensation being conducted in a conventional manner to completion.
