PURPOSE:To obtain the title composition which retains mechanical properties inherent in resin and has excellent sliding characteristics and good moldability by incorporating a polymer grafted with an organopolysiloxane into a thermoplastic polyester resin. CONSTITUTION:70-93wt.% thermoplastic polyester resin is mixed with 30-7wt.% polymer prepared by graft polymerization of an organopolysiloxane onto a thermoplastic resin (e.g. a polymer prepared by graft polymerization of an organopolysiloxane onto polyethylene methyl methacrylate and having a silicone content of 60%), giving a lubricating resin composition. This composition gives a molded article having excellent sliding characteristics while retaining mechanical properties inherent in synthetic resin; it has good moldability and is inexpensive; therefore, it is most suitable for bearing material, etc. |
