摘要：
A high molecular weight aromatic polyamide molding composition prepared by the polycondensation reaction of:(A) An aromatic diamine of the formula:H.sub.2 N--AR'--O--Ar"--CO--Ar"--O--Ar'--NH.sub.2wherein Ar' and Ar" are meta- or para-phenylene, and wherein up to 70 mole % of said aromatic diamine can be replaced by a second aromatic diamine having the formula:H.sub.2 N--Ar--((Z).sub.q --Ar).sub.r --NH.sub.2wherein Ar is meta- or para-phenylene, Z is identical or different radicals selected from the group consisting of --O--, --S--, --SO.sub.2 --, --CO--, and --C(CH.sub.3).sub.2 --, q is 0 or 1, and r is 0, 1 or 2, with(B) An aromatic dicarboxylic acid selected from the group consisting of:(i) isophthalic acid, wherein up to 60 mole % of said isophthalic acid may be replaced with terephthalic acid, wherein said isophthalic acid and said terephthalic acid may be ring substituted with one or more substituents selected from the group consisting of C.sub.1-6 alkyl, phenyl, alkyl or aryl substituted phenyl, C.sub.1-6 alkoxy, phenoxy, alkyl or aryl substituted phenoxy and halogen substituents;(ii) a dicarboxylic acid of the formula ##STR1## (iii) a dicarboxylic acid of the formula:HO.sub.2 C--Ar--(A--Ar).sub.p --CO.sub.2 Hwherein Ar is meta- or para-phenylene, A is --O--, --S--, --SO.sub.2 --, or --CO--, and p is 0 or 1; and mixtures thereof.
