PROBLEM TO BE SOLVED: To obtain a resin composition excellent in melt tension and impact resistance by including a styrene resin with at least either of (oxidized) polyethylene wax and (oxidized)polypropylene wax and at least either of a fatty acid metal salt and an amido- or ester-group-containing lubricant. SOLUTION: This composition contains 100 pts.wt. styrene resin composition or filled styrene composition, 0.1-10 pts.wt. at least either of (oxidized) polyethylene wax and (oxidized)polypropylene wax, and 0.1-10 pts.wt. at least either of a fatty acid metal salt and an amido- or ester-group-containing lubricant having an average molecular weight of at most 10,000 and has a melt tension of 5-20 g at 200 deg.C and an extrusion rate of 20 mm/min). The fatty acid metal salt is exemplified by sodium stearate or zinc stearate, and the amido- or ester-group-containing lubricant is exemplified by ethylene bisstearamide or montanic ester wax. |
