Abstract

PURPOSE:To produce a block copolymer excellent in heat resistance, chemical resistance and high-temperature mechanical properties, by copolymerizing polyphenylene sulfide with polyphenylene sulfide sulfone by a specified two-stage reaction. CONSTITUTION:A block copolymer comprising polyphenylene sulfide (PPS) segments and polyphenylene sulfide sulfone (PPSS) segments and having an inherent viscosity [eta] as measured in alpha-chloronaphthalene at 206 deg.C in a polymer concentration of 0.4g/100ml solution and determined according to the equation] in the range of 0.03-1.0 is produced either by reacting a mixture of previously synthesized prepolymer of PPS with a dihalodiphenyl sulfone and a sulfiding agent, or by reacting a mixture of a previously synthesized PPSS prepolymer with a polyhaloaromatic compound and a sulfiding agent. A resin having both of heat resistance and chemical resistance inherent in PPS and good high- temperature mechanical properties inherent in PPSS can be obtained.
