【摘要】 通过加入复合抗氧剂A(酚类 )、B(亚磷酸酯类 )及流动改性剂 (液体石蜡 ) ,采用热引发熔融接枝法制备马来酸酐接枝SBS ,获得了具有较高接枝率 ( 0 .5 2 % )和较好熔体流动性且不含凝胶的马来酸酐接枝SBS产物。用该产物增韧PA66,获得了较好的增韧效果更多还原

【Abstract】 Maleic anhydride(MAH)grafted SBS(SBS-g-MAH) was prepared by thermal initiation melt grafting in the presence of complex antioxidant of phenol type and phosphite ester type and flowability modifier of paraffin.Gel-free SBS-g-MAH with higher grafting rate and better flowability is obtained.SBS-g-MAH has better toughening effect on PA66.更多还原
