| Abstract: |
| 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. |
