PURPOSE:To form a rubber-modified styrene resin compsn. having excellent impact resistance as well as surface gloss, by incorporating dispersed particles of a rubbery polymer and a fluorinated compd. oil in a compsn. CONSTITUTION:A rubber-modified styrene resin compsn. contains a rubbery polymer as dispersed particles. This compsn. contains 3-12wt.% rubbery polymer and the dispersed particles have an average particle size of 0.5-1.5mum. This compsn. also contains 0.001-0.3wt.% fluorinated compd. oil having a surface tension not higher than 25dyne/cm at 25 deg.C. Examples of the fluorinated compd. oil are fluorocarbon compd. oil, perfluoroether oil, etc.
