POLYSTYRENIC RESIN COMPOSITION, SHEET AND CONTAINERS COMPOSED OF THE SAME

摘要

PURPOSE:To obtain the subject composition, excellent in molding processability, slipperiness and suppressing effects on foaming and suitable as containers such as a cup for beverages by including a specific amount of a silicone compound in a PS-based resin. CONSTITUTION:The objective composition is obtained by including (B) 0.1-10.0wt.% silicone compound which is a comb type graft polymer prepared by reacting an organosilicon compound having >= one hydroxyl groups with a >=18C hydrocarbon compound having >= one double bonds reactive with the hydroxyl groups in (A) a PS-based resin. Furthermore, a sheet excellent in slipperiness is obtained from this composition.
