摘要:
使用5-叔丁基-1，3-二（2-氯代异丙基）苯/四氯化钛引发体系，通过可控活性正离子聚合反应制备了含双活性链末端的聚异丁烯，再使用1，3-丁二烯封端制备具有烯丙基氯末端结构的聚异丁烯，并结合四丁基氢氧化铵存在条件下水解的方法制备了双端羟基遥爪聚异丁烯，研究了封端时间对封端反应的影响，探讨了所得聚合物的热稳定性和低温性能。结果表明，在四丁基氢氧化铵存在条件下，由含氯链末端亲核取代方式制备所得聚合物的端羟基转化率高，反应时间短，原料便宜易得且制备工艺简便，所得产物的热稳定性及低温性能优良。
Abstract:
Polyisobutene with double living chain terminal was prepared by controlled living cationic polymerization using 5-tert-butyl-1,3-bis(2-chloroisopropyl) benzene/titanium tetrachloride initiator system, polyisobutene with allyl chloride terminal structure was prepared with 1,3-butadiene as end-capping agent, and then double hydroxyl-terminated telechelic polyisobutene was prepared via the hydrolysis of polyisobutene with allyl chloride terminal structure in the presence of tetrabutylammonium hydroxide. The effect of end-capping time on endcapping reaction was studied, and the thermal stability and low temperature property of the resulting polymer were discussed. The results showed that in the presence of tetrabbutylammonium hydroxide, the polymer with hydroxyl- terminated group prepared via nucleophilic substitution method of chlorine-containing chain terminal had high conversion rate, reaction time was short, the raw materials were cheap and easily available, the preparation process was simple and convenient, and the resulting polymer had excellent thermal stability and low temperature performance.
