研究了乙烯/1-辛烯共聚物(POE)增韧尼龙6(PA6)在不同温度下的脆韧转变。实验结果表明，临界粒子间距(IDC)与POE含量无关，在较低温度下的POE粒子尺寸远低于PA6的脆韧转变温度(T？BDM)。然而，在较高的温度下，特别是接近T？BDM的温度下，IDC取决于POE颗粒的大小。这表明，吴的橡胶增韧判据，特别是IDC是与橡胶体积分数和颗粒大小无关的基体的材料性质，在较高温度下不适用于POE增韧PA6的脆韧转变。(C)2012年威利期刊公司J.Appl。波兰姆。《科学》，2013
The brittleductile transition of ethylene/1-octene copolymer (POE) toughened polyamide 6 (PA6) was studied at various temperatures. The experimental results show that the critical interparticle distance (IDc) is independent of the POE content, and the POE particle size at lower temperatures, that is, the temperature is much lower than the brittleductile transition temperature (T?BDm) of PA6. At higher temperatures, however, especially temperatures close to the T?BDm, the IDc depends on the POE particle size. This indicates that Wu's criterion for rubber toughening, specifically that the IDc is a material property of the matrix, independent of rubber volume fraction and particle size, is inapplicable at higher temperatures for the brittleductile transition of the POE toughened PA6.
