With TB as a sensitizer and various alcoholamine as donors, the photoredox of TB and the polymerization kinetics of AM induced by He-Ne laser were investigated. It was found that either for the photoredox of TB or for the polymerization of AM, the activity of alcoholamine increases in the order of EOA<DEOA <TEOA in TB-alcoholamine sensitized system. The overall apparent kinetic equations of AM polymerization at 30℃ have been determined. In addition, the molecular weights under various conditions was measured.展开更多
