用重氮盐引发N-乙烯咔唑之光聚合研究

STUDY ON THE PHOTOPOLYMERIZATION OF N-VINYLCA- RBAZOLE INITIATED BY 4-N,N-DIETHYLAMINOBENZENE DIAZONIUM FLUOROBORATE

聚N-乙烯咔唑[P(N-VCz)]是典型的有机光导体,已被广泛应用于静电照相和光导热塑全息记录中。 N-乙烯咔唑是一种聚合活性较大的单体,聚合反应可通过自由基、阳离子、Zeigler-Natta型催化剂和电荷转移引发等途径进行。 已有报道,芳香族重氮盐可作为光聚合引发剂。如对环氧化合物。

Photopolymerization of N-vinylcarbazole initiated by 4-N,N-diethylaminobenzene diazo-nium fluoroborate has been studied. Based on the solvent and retarder effect as well as spectrum measurement, a cationic initiation mechanism was suggested.
