ABSTRACT:
Described herein are blends having increased crystallization rates comprising (a) at least 98 percent by weight of a poly(aryl ether ketone) having a melting point no more than about 390.degree. C., and (b) 2 percent by weight or less of another poly(aryl ether ketone) having a melting point higher than about 400.degree. C. The blends retain their attractive crystallization behavior even after prolonged treatment in the melt. The blends of this invention may be fabricated into any desired shape, for example, moldings, coatings, films, fibers, and particularly, for use as electrical insulation for electrical conductors.
