Abstract:
A heat-resistant, chemical-resistant polyphenylene sulfide block copolymer containing polyphenylene sulfide units and aromatic polyester units, wherein the polyphenylene sulfide units have a number average molecular weight in the range of 6,000 to 100,000. Provided is a polyphenylene sulfide block copolymer that overcomes the disadvantages of block copolymers including a low-molecular-weight polyphenylene sulfide segment and having poor heat resistance and chemical resistance.
