PURPOSE:To obtain a resin composition, containing a styrene-based polymer, polyethylene oxide and a specific sulfonate in a specified proportion, having excellent antistatic properties and good in molding processability. CONSTITUTION:The objective composition containing (A) 100pts.wt. styrene-based polymer, (B) 3-35pts.wt., preferably 5-20pts.wt. polyethylene oxide having 50,000-1,000,000, preferably 100,000-500,000 number-average molecular weight and (C) 0.5-5pts.wt., preferably 0.7-3pts.wt. sulfonate expressed by formula (R1 and R2 are H Or 1-12C alkyl; X is Na, Li or K) (e.g. sodium dodecylbenzenesulfonate). |
