Patent number: 5084530Abstract: Novel poly(aryl ether sulfone)-poly(aryl ether ketone) block copolymers are described. They are prepared by the nucleophilic polycondensation of a hydroxy- or halo-terminated poly(aryl ether ketone) oligomer with the poly(aryl ether sulfone) forming reagents; alternatively, a preformed poly(aryl ether sulfone) block may be used.The novel copolymers are tough materials with excellent heat, solvent, and stress-crack resistance. They display high HDT's (heat distortion temperatures) and are useful in molding, extrusion and composites applications.Type: GrantFiled: August 3, 1990Date of Patent: January 28, 1992Assignee: Amoco CorporationInventors: Markus Matzner, James H.

Patent number: 4959423Abstract: 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.Type: GrantFiled: May 9, 1988Date of Patent: September 25, 1990Assignee: Amoco CorporationInventors: James E.
