Abstract
A rubber-modified styrene type resin composition excellent in sliding properties which comprises 100 parts by weight of a rubber-modified styrene type resin and 2.2 to 3.2 parts by weight of dimethyl silicone oil having a viscosity ranging from 5,000 to 15,000 centistokes at 25.degree. C., the styrene type resin comprising 3 to 8% by weight of a rubber-like polymer which is present in the form of microgels having an average particle size ranging from 0.6 to 1.2 micron, and having an intrinsic viscosity of 0.53 to 0.65 and the content of methanol-soluble matter in the range of from 0.5 to 1.5% by weight, is herein disclosed. The rubber-modified styrene type resin composition is excellent in its sliding properties and thus does not provide a molded product having poor appearance during molding. The rubber-modified styrene type resin composition is used to form mechanical parts in the fields of household appliances and OA apparatuses.
