CRYSTALLINE COPOLYAMIDE FROM TEREPHTHALIC ACID, ISOPHTHALIC ACID AND C6 DIAMINE

摘要

ABSTRACT OF THE DISCLOSURENovel crystalline copolyamides are obtained fromterephthalic acid, isophthalic acid, hexamethylenediamineand trimethylhexamethylenediamine and filled molding com-positions prepared therefrom. These compositions haveheat deflection temperatures of about 240 to about 305°Cand are useful in molding applications.
