RESIN COMPOSITION AND MOLDED ARTICLE

摘要

The present invention aims to provide a resin composition capable of providing a molded article having both a low coefficient of kinetic friction and a high limiting PV value. The resin composition of the present invention includes an aromatic polyether ketone resin (I) and a fluororesin (II). The fluororesin (II) is a copolymer of tetrafluoroethylene and a perfluoroethylenic unsaturated compound represented by the following formula (1):
€ƒ€ƒ€ƒ€ƒ€ƒ€ƒ€ƒ€ƒCF 2 =CF-Rf 1 €ƒ€ƒ€ƒ€ƒ€ƒ(1)
wherein Rf 1 represents -CF 3 or -ORf 2 , and Rf 2 represents a C1-C5 perfluoroalkyl group. The aromatic polyether ketone resin (I) and the fluororesin (II) satisfy a ratio (I):(II) by mass of 95:5 to 50:50. The aromatic polyether ketone resin (I) and the fluororesin (II) satisfy a melt viscosity ratio (I)/(II) of 0.3 to 5.0. The fluororesin (II) is dispersed as particles in the aromatic polyether ketone resin (I). The fluororesin (II) has an average dispersed particle size of smaller than 3.0 µm.
