研究了反式－1，4－聚异戊二烯（TPI）的硫化特性及硫化程度对其力学性能的影响。结果表明：采用硫黄－促进剂CZ硫化体系时，TPI的硫化曲线较为理想；硫化使得TPI的力学性能在硫黄用量达到一定值时发生突变，由硬质材料转变为软质橡胶，即从硫化三阶段中的第二阶段过渡到第三阶段。

Vulcanization character of trans－ 1,4－ polyisoprene(TPI) and effect of vulcanization degree on mechanical properties of vulcanized TPI were studied. The results showed that among three conventional kinds of accelerator (M,CZ and TT ), vulcanization curve of TPI with CZ as accelerator was ideal. Vulcanized TPI changes suddenly from hard material to soft elastic rubber when the sulfur content increased from 4 phr to 5 phr. The addition of carbon black could improve the tensile strength of the rubber obviously.
