摘　　要：试验研究新型活化体系(助剂B/硬脂酸)替代传统活化体系(氧化锌/硬脂酸)对反式1,4-聚异戊二烯(TPI)硫化胶性能的影响。结果表明:与传统活化体系相比,采用新型活化体系的TPI硫化胶的结晶度提高约50%,结晶温度升高约30℃;在新型活化体系中,助剂B用量为2份时,TPI硫化胶的综合物理性能最佳。The effect of a new type of activation system（additive B/stearic acid） on the properties of trans-1,4-polyisoprene（TPI） vulcanizates were experimentally investigated,and compared with traditional activation system（zinc oxide/stearic acid）.The results showed that,with a new activation system,the crystallinity of TPI vulcanizates increased by about 50%,and the crystallization temperature increased by about 30 ℃.When the addition level of additive B was 2 phr,the comprehensive physical properties of TPI vulcanizates were the best.
