摘　　要：采用自由基聚合的方法,将季铵离子液体(乙烯基苄基三乙基氯化铵)和对苯二乙烯聚合到一起,制备了一种聚离子液体PAD-X,并研究了其在CO2和环氧氯丙烷环加成的反应中的催化性能。结果表明,PAD-1在无溶剂、无助催化剂、温和条件下可高效催化转化CO2。最佳的反应条件为0.1MPa、70℃和24h,此条件下环氧氯丙烷的转化率为94.3%,生成目标产物氯丙烯碳酸酯的选择性为99.5%。Poly(ionic liquid)s(PAD-X) were prepared by free radical polymerization from the quaternary ammonium ionic liquid(vinylbenzyltriethylammonium chloride) and divinylbenzene, and their catalytic performances in the cycloaddition of CO2 and epichlorohydrin were investigated. The results indicate that PAD-1 can catalyze the conversion of CO2 efficiently under mild conditions without solvent and cocatalyst. Under the optimized reaction conditions, 0.1 MPa, 70℃ and 24 h, the yield and selectivity of chloropropene carbonate are 94.3% and 99.5%, respectively.
