The cation-scavenging reaction has been directly observed by using the pulse radiolysis method for cation radicals of both N-vinylcarbazole (VCZ+·; the initiating species of radiation-induced cationic polymerization of VCZ) and N-ethylcarbazole (EtCZ+·, nonpolymerizing model compound) in order to elucidate the role of inhibitors in radiation-induced cationic polymerization. The rate constants for the reactions of VCZ+· with triethylamine, diphenylamine, and dimethylaniline in nitrobenzene solution have been determined to be 1.3 × 109, 2.0 × 109, and 3.9 × 109 M-1 s-1, respectively, which are almost the same as those for EtCZ+· with these three scavengers.
