摘要：采用一步法和母料法制备了动态硫化ＰＰ／ＥＰＤＭ ，进行了材料拉伸行为的研究，结果表明，分散相ＤＰＤＭ 可提高材料的延伸性和韧性，ＰＰ 的分子量决定了Ｆｔ、σｙ 和σｐ；而拉伸后期是否出现σｂ 和εｔ 的二次屈服，则和ＥＰＤＭ 的交联和形态有关。采用母料法和并用助交联剂，可达到增韧和保持刚性的目的。
s Dynamic vulcanized PP/EPDM was prepared by means of one stage process and masterbatch process,and the tensile behavior of the prepared blend were studied.The results showed the disperse phase EPDM could improve the extensibility and toughness of the blend,but the E t,σ y and σ p were determined by the molecular weight of PP;whether there would be a second yield in the late tensile,it was depended on the degree of cross-linking and morphological structure of EPDM.The use of masterbatch and compound crosslinking agent had toughening and rigidity effects on the blend.
