Biodegradable lubricative resin composition

摘要

A biodegradable lubricative resin composition which withstands use as a material for sliding parts, and slide bearings and gears made from such a resin composition. The resin composition contains an aliphatic polyester which is a monopolymer or copolymer of a hydroxy-carboxylic acid or an aliphatic polyhydroxy alcohol and an aliphatic polybase, the aliphatic polyester preferably containing 50-100 wt % lactic acid, and a lubricant which is a lubricating oil or a solid lubricant. Slide bearings and gears molded from such a resin composition are also proposed.
