摘　　要：采用孟山都加工性能试验仪研究了反式 1,4 聚异戊二烯 (TPI)及其混炼胶的流变特性。结果表明 ,TPI表观粘度 ηa 高于NR ,SBR和BR ,并随着剪切速率的增大或温度的升高而减小 ;TPI的粘流活化能ΔEη 与NR相近 ,比BR和SBR高 ;在TPI与NR ,SBR和BR并用胶料中加入加工助剂可使加工性能得以改善。The rheological properties of TPI and its mix were investigated with Monsanto processibility tester.The results showed that the apparent viscosity η a of TPI increased faster than those of NR,SBR or BR and decreased as the shear rate or temperature increased;the active energy of viscous flow ΔE η for TPI was similar to that for NR and higher than those for BR or SBR;and the processibility of TPI,NR,SBR or BR mixes were improved with the addition of processing aids.
