Abstract: PURPOSE:To provide the titled molding having high thermal distortion temperature and excellent heat-resistance, by melt-molding polyarylene sulfide resin and by subsequent thermal treatment. CONSTITUTION:A polyarylene sulfide resin having a repeating unit of -(Ar-S)- (where Ar is a divalent aromatic radical containing a 6C-membered ring) as a main constructional unit is melt-molded. The moldings are then heated at 250- 280 deg.C for 10hr. By this thermal treatment a thermal distortion temperature can be enhanced by at least 30 deg.C, and a good heat-resistant molding is obtained. If the thermal treatment temperature is =280 deg.C a size distortion of the molding occurs unfavorably. If a thermal treatment time is

Abstract: PURPOSE:To provide a polymer compsn. in which impact resistance is improved, by a method wherein a polar elastomer is blended witha polyarylene ether sufone- polyamide block copolymer. CONSTITUTION:50-3pts.wt. of a polar elastomer is blended with 50-97pts.wt. of a polyarylene ether sulfone-polyamide block copolymer in such a proportion that the combined amount of the elastomer an the blocked copolymer becomes 100pts.wt. The polyarylene ether sulfone used in a linear polymer composed of an arylene linkage, an ether linkage and a sulfone linkage in combination with one another. When the amount of the elastomer is below 3pts.wt., there can be obtd. little effect on the improvement of impact resistance. It is preferred to use the elastomer in an amount of more than 50pts.wt. because the thermal properties ans the mechanical properties of the block copolymer are greatly reduced.
