PURPOSE:To provide an oil-contg. synthetic resin compsn. which is suitable for use in the production of bearings, has excellent frictional and wear characteristics and does not cause the separation of components during molding, by blending a liquid lubricant, a higher fatty acid auxiliary and a nonionic surfactant with a synthetic resin. CONSTITUTION:2-15pts.wt. liquid lubricant such as turbine oil or silicone oil, 0.1-2pts.wt. one or two members selected from higher fatty acids (salts) and higher fatty acid alkyl esters (e.g. zinc or butyl stearate) and 0.2-15pts.wt. nonionic surfactant (e.g. alkylphenol or sorbitan ester surfactant) are blended with 100pts.wt. synthetic resin such as polyacetal or polyamide to obtain the desired oil-contg. synthetic resin compsn. This resin compsn. is freed from problems such as separation of the liquid lubricant during molding or insufficient bite of the resin compsn. into the screw of an injection molding machine.
