摘要:
Described are blends of a crystalline poly(aryl ether ketone) and a polyarylate and/or a liquid crystalline polyarylate. These blends exhibit improved mechanical properties and environmental stress rupture resistance.
摘要:
Described herein are isomorphic blends of poly(phenylene oxide) and poly(aryl ether ketones) having less than about 30 mole percent and preferably less than about 25 mole percent of keto groups based on the total keto and ether groups. The blends are particularly desirable for use as an electrical insulation for electrical conductors.
