摘要:
Process for the preparation of copolyamides from adipic acid, terephthalic acid and hexamethylene diamine containing 25-48% by weight of units of hexamethylene terephthalamide, by precondensing the monomers at a temperature of at least 250.degree. C. and a pressure of at least 35 bar and completing the polycondensation in the usual manner.
