摘要：

Catalytic activities of benzyl sulfonium salts with nonnucleophilic anions (BF//4** minus , PF//6** minus , AsF//6** minus , SbF//6** minus ) for epoxy polymerization were examined. The order of reactivities correlated well with nonnucleophilicity of anions. Epoxy resins catalyzed by these salts are characterized by longer shelf-life and shorter gel time at high temperature. Some physical properties of cured product were compared with those cured by a commonly used BF//3 amine complex.
