中文摘要:
      研究了混炼工艺对聚亚丙基碳酸酯(PPC)/SBR共混物性能的影响。结果表明，采用混炼工艺A(SBR+PPC→配合剂→陈化12 h→MA→返炼→硫化)，可在提高硫化体系活性的基础上消除陈化对共混物拉伸性能的影响；将PPC与SBR预混后混炼，可提高共混物的定伸应力和硬度，降低扯断永久变形；停放时间延长(2 h以内)有利于共混物性能的提高；薄通次数增加对共混物性能无显著影响。
英文摘要:
      The influence of mixing procedure on the properties of PPC/SBR blend was investigated.The results showed that the aging effect on the tensile strength of PPC/SBR blend was eliminated by using the mixing procedure A(SBR+PPC→compounding ingredients→aging for 12 h→MA→remilling→curing )while the activity of curing system increased；the modulus and hardness of the blend increased，and its tensile set at break decreased as PPC/SBR blend was premixed；the better properties of the blend was beneficial from the longer conditioning time(up to 12 h)；the increase of mill runs had no significant effect on the blend properties.
