中文摘要:
      研究原位反应生成甲基丙烯酸钠(NaMAA)对采用不同共混方式混炼的NBR/EPDM并用胶性能的影响。结果表明，NBR与EPDM共混后，随着NaMAA理论生成量的增大，硫化胶的邵尔A型硬度、定伸应力和撕裂强度等均不断增大；拉伸强度在NaMAA理论生成量为40份时达到最大值，为31.8 MPa。与EPDM母胶法制备的并用胶相比，直接法NBR/EPDM并用胶共混性能较好，物理性能更佳。
英文摘要:
      The influence of the in-situ synthesized sodium methacrylate on the properties of NBR/EPDM blend mixed by different mixing processes was investigated.The results showed that the Shore A hardness，modulus and tear strength of the vulcanizate increased as the theoretical yield of NaMAA increased；the best tensile strength was 31.8 MPa when theoretical yield of NaMAA was 40 phr.The mixing property and physical properties of the blend with direct mixing process were better as compared with those of the blend with EPDM masterbatch technique.
