PURPOSE:To obtain a rubber-modified polystyrenic resin composition, having high impact resistance and excellent in surface characteristics such as surface gloss. CONSTITUTION:The objective composition is obtained by adding 0.5-5.0wt.% polyethylene and 0.02-0.5wt.% polydimethylsiloxane having 500-60,000 cSt viscosity at 25 deg.C to a rubber-modified polystyrenic resin. This composition contains 1-15wt.% rubbery polymer, which is dispersed in a particulate shape. The average particle diameter of the dispersed particles is 0.1-1.5mum. |
