Abstract
A styrene resin composition excellent in sliding properties which comprises 100 parts by weight of a styrene polymer, 2.0 to 4.0 parts by weight of dimethylsilicone oil having a viscosity ranging from 5,000 to 15,000 centistokes at 25.degree. C. and 0.05 to 8 parts by weight of maleic anhydride monomer or 0.05 to 50 parts by weight of a maleic anhydride-styrene copolymer containing at least 5% by weight of maleic anhydride monomer units is herein disclosed. The styrene resin composition is excellent in sliding properties and thus does not provide a molded product having poor appearance during molding. The styrene resin composition is used to form mechanical parts in the fields of household appliances and office automation apparatuses.
