ABSTRACT:
Novel copolyamides having the recurring unit ##STR1## are disclosed wherein x, in 50 percent to 85 percent of the recurring units, is an integer from 6 to 10 inclusive, and, in 15 percent to 50 percent of the recurring units is 4, and Ar is an arylene radical. The copolyamides are characterized by ease of melt processing such as in molding, extruding, and injection molding, while at the same time possessing good physical properties, and being further characterized by their ease of conversion from the amorphous to the crystalline state which, in turn, gives rise to a high degree of versatility in their fabrication.
