摘　　要：以聚异戊二烯为原料 ,在对甲苯磺酸的催化作用下制备环化聚异戊二烯。研究了聚异戊二烯的浓度、催化剂用量、反应温度和反应时间等工艺条件对聚异戊二烯环化反应产物的影响。Cyclized polyisoprene was synthsized from polyisoprene with p-toluenesulfonic acid as catalyst. The influence of reaction conditions such as the concentration of polyisoprene, the quantity of catalyst, reaction temperature and reaction time on the cyclized polyisoprene was discussed.

关 键 词：聚异戊二烯 环化反应 橡胶
