摘要： A polyorganosiloxane-type thermoplastic resin having excellent slidability, abrasion resistance, weatherability, impact strength, fatigue resistance and chemical resistance is disclosed. The thermoplastic resin comprises a graft copolymer (IV) obtained by graft-polymerizing at least one vinyl monomer (v) onto a modified polyorganosiloxane obtained by polymerizing 80 to 99.8% by weight of an organosiloxane (I) having the structural unit described thereinabove, 0.1 to 10% by weight of at least one graft crosslinking agent (II) containing an alkoxysilyl group, selected from the group consisting of a vinyl-type graft crosslinking agent, a mercapto-type graft crosslinking agent, an acryloyl-type crosslinking agent and a vinylphenyl-type crosslinking agent, and 0.1 to 10% by weight of a compound (III) having two alkoxysilyl groups, provided that (I)+(II)+(III)=100% by weight.
