ABSTRACT:
Described herein are miscible poly(aryl ether ketone) blends possessing increased crystallization rates. The novel compositions contain (a) from about 98 to about 99.9 percent by weight of a miscible poly(aryl ether ketone) blend, and (b) from about 0.1 to about 2 percent by weight of a poly(phenylene sulfide) or a copolymer thereof. The compositions of the instant invention retain their attractive crystallization behavior even after prolonged treatment in the melt. Moreover, these compositions display excellent mechanical properties as well as excellent chemical and heat resistance.
