摘　　要：采用机械共混方法对小本体聚丙烯进行了增韧改性研究,探讨了增韧剂种类、含量以及有少量聚乙烯存在下对聚丙烯共混体系力学性能的影响,并与连续法聚丙烯进行了比较。实验结果表明,聚丙烯/增韧剂/聚乙烯三元共混体系可以获得理想的增韧效果。The toughening modification of small scale bulk polypropylene has been studied mechanical blending method. The effect of type and content of different toughening agents and a little PE on the mechanical properties of FF blends has been discussed with comparison with polypropylene of continuous polymerization. The experimental results have shown that the three components blends(PP/toughening agent/PE) displayed ideal toughening effect.
