摘　　要：比较了不同的动态硫化工艺和硫化体系对聚丙烯（PP）／三元乙丙橡胶（EPDM）共混物性能的影响。结果表明，当EPDM加入量小于30％时，用双螺杆挤出机动态硫化比用双辊开炼机动态硫化效果更好。以过氧化苯甲酸（BPO）为硫化剂，加工条件容易控制，并可得到综合性能较好的PP／EPDM共混物。Effectiveness of different dynamic sulfurization processes and sulfurization systems to the properties of polypropylene (PP) / ethylene-propylene diene copolymer (EPDM) blends is compared. The result shows that when addition of EPDM is less than 30%, the dynamic sulfurization result is better by using double-screw extruder than by using double-roller blending rolls. With benzoyl pernxide (BPO) as vulcbozing agent, the processing conditions are controlled easily and can obtain PP/EPDM blends with good integrated properties.
