Abstract:
A polyphenylene sulfide block copolymer contains polyphenylene sulfide units and polyorganosiloxane units and has a glass-transition temperature in the range of 80° C. or lower and a weight-average molecular weight in the range of 35,000 to 100,000. The polyphenylene sulfide block copolymer has high flexibility as well as high heat resistance and heat aging resistance.
