PURPOSE:A styrenic resin composition having improved oil resistance, obtained by adding an alkylamine derivative to a composition consisting of a styrenic resin having <= a specific melt flow index and a styrene-butadiene block copolymer. CONSTITUTION:[A] 100pts.wt. total amounts of (i) 90-10pts.wt. styrenic resin having <=3g/10min melt flow index (JIS-K 6870) and (ii) 10-90pts.wt. styrene- butadiene block copolymer having preferably 30-75wt% styrene is blended with [B] 0.01-10pts.wt., preferably 0.1-3pts.wt. alkylamine derivative [e.g., compounds shown by the formula I -formula III (R is 8-30C alkyl)], to give the desired composition. The composition is usable as containers such as cups, trays, etc. requiring oil resistance. |
