摘要
聚丙烯/EPDM共混物韧性的测定可以在很宽的温度(25～132 ℃)和组分(EPDM质量分数为0～26%)中进行.发现了增加温度和增加EPDM组分对EPDM增韧的聚丙烯的脆韧转变有相同的影响,发现了聚丙烯/EPDM共混物的脆韧转变温度与EPDM组分之间的相互关系以及聚丙烯/EPDM共混物的拉伸强度和断裂伸长率与EPDM组分之间的相互关系.
The toughness of PP/EPDM blends was measured over a wide range of temperature（25-132 ℃ ） and content （0 - 26wt % EPDM）. It was found that incteasing temperature and increasing EPDM content have equivalent effects on the brittle- tough transition of toughening PP with EPDM. Acorrelation was found between the brittle- tough transition tempetature of PP/EPDM blends and EPDM content . It was found that increasing EPDM content, the tensile strength became low. The correlation was found beteen PP/EPDM blends and EPDM content.
