摘　　要：建立了异丁烯阳离子聚合的水分子模型反应。采用高效液相色谱定量分析方法，阐明了模型反应机理，研究了第三组分在异丁烯阳离子聚合体系中的作用，证实了在异丁烯阳离子聚合体系中第三组分主要起质子捕获剂的作用，并且其质子捕获能力与其用量及加料方式有关。The model reaction of isobutylene cationic polymerization has been established. The products is analyzed by high pression liquid chromatography (HPLC) to state the mechanism of model reaction, and the mechanism of the third component in cationic polymerization system of isobutylene is studied. It is found that the third component is proton trap in the system, the capability of proton trap is influenced by quantity and the adding approach.
