| Abstract: | 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. |
