Abstract
Provided are heat-stable polyphase polyamido compositions having improved mechanical properties which comprise (i) from 50 to 99% by weight of a nylon polyamide resin matrix and (ii) from 1 to 50% by weight of a particulate disperse phase comprising a polyamide incompatible with the polyamide resin matrix, and methods for the preparation thereof. Shaped articles comprising said compositions exhibit improved physical properties, particularly with regard to impact strength.
