ABSTRACT:
Heat-stable polyphase polyamido compositions having improved mechanical properties are comprised of (i) from 55 to 99% by weight of a nylon polyamide resin matrix, said polyamide resin having a number-average molecular weight of at least 5,000, and (ii) from 1 to 45% by weight of a particulate disperse phase, said particulates having a particle size ranging from 0.01 to 10.mu., and said disperse phase comprising a polyesteramide having a content in amide groups of less than 40% of the amide groups comprising said polyamide matrix resin and a glass transition temperature of less than 5.degree. C.
