This invention pertains to novel copolyesters consisting essentially of units (I), (II), (III), and (IV). ##STR1## and blends of these polymers and articles made from both. Units (I), (II), (III), and (IV) are present in specified proportions as defined in the 'Description of the Invention.' The instant copolyesters display orientation in the molten state, good fiber ratings and high strength; they have melting points in the range of from about 340.degree. to about 400.degree. C. and are melt-processible. Advantageously, these compositions filled with about 30 weight percent of glass fibers display heat distortion temperatures of over 240.degree. C. up to about 280.degree. C. and higher, when measured under a load of 264 psi. When blended, certain properties are improved, particularly they are easier to melt fabricate, have a decreased tendency to blister and increased strength. These polymers and blends may be used advantageously in ovenware, electronic components, electrical equipment, and other end uses requiring high temperatures.

This invention pertains to novel copolyesters consisting essentially of units (I), (II), (III), and (IV). ##STR1## and blends of these polymers and articles made from both. Units (I), (II), (III), and (IV) are present in specified proportions as defined in the 'Description of the Invention.' The instant copolyesters display orientation in the molten state, good fiber ratings and high strength. Advantageously, the polymers of the present invention display a significant improvement in viscosity and moldability of the neat polymer. The polymers have excellent mechanical and surface properties including blister resistance, strength, toughness, and ability to vapor phase solder, and form strong fibers while still maintaining a high heat distortion temperature. They have melting points in the range of from about 250.degree. to about 360.degree. C. and are melt-processible. Advantageously, these compositions filled with about 30 weight percent of glass fibers display heat distortion temperatures of up to 240.degree. C., when measured under a load of 264 psi. The polymers may be blended to tailor properties. These polymers and blends may be used advantageously in producing fibers and in electrical equipment, electronic components and other end uses requiring moderately high temperatures.

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.
