摘要: PURPOSE: The combination use of two kinds specific styrene-butadiene block copolymer and a shock-resistant polystyrene gives the titled composition with high transparency as well impact strength becauses no crack develops in crosswise direction, even when it is extruded. CONSTITUTION: 88W50pts.wt. per 100pts. resultant composition, general- purpose polystyrene, 5W20pts. linear containing more than 60wt% styrene, different less styrene 2W10, preferably 3W 8pts. melt index 1W10g/10min, weight- average molecular weight 100,000W300,000 rubber content some 5W 7wt% are combined. USE: suitably used material for molding thin-wall vessels. COPYRIGHT: (C)1981,JPO&Japio
