| 摘 要： | 研究了乙烯-1-辛烯共聚物(POE)对两种不同型号的聚丙烯(PP)的增韧情况。结果显示,对不同性质的基体PP,出现脆韧转变所需的弹性体POE含量不同;根据逾渗模型,应用不同的计算公式,定量地求得了两种PP/POE体系分别出现脆韧转变时的临界基体层厚度Tc。

| Abstract: | The toughening effects of Metallocene Ethylene-1-Octene Copolymer(POE) on two different types of Polypropylene(PP) were investigated.It is shown that,for different PP matrices,the POE content is different in order to reach the Brittle-Ductile Transition(BDT).According to the percolation model and various calculation equations,the Critical Matrix Ligament Thickness(Tc) of two PP/POE blends were calculated quantitatively. |

| Keywords: | PP POE brittle-ductile transition critical matrix ligament thickness |
