摘要

正

Several dimethylamino-substituted chalcone （i .e. dimethylaminobenzal acetophenone）（DBA） derivatives with intramolecular charge transfer transition character were used as visible light sensitizers for radical photopolymerization initiated by iodonium salt （DPIO）. Initiating radical species is produced from DBA sensitized photolysis of DPIO through the single electron transfer

accompanying the bleaching of DBA

The activity of DBA decreases as a function of substituent attached to phenyl ring in the order: DBA-2 （OCH

）

DBA-1（H）

DBA-3 （Cl）. The kinetic study on photopolymerization of MMA was carried out in CH

CN solution at 30 ℃by dilatometry. The polymerization rate was determined to be proportional to the concentration with exponents of 0.42

0.25 and 0.86 for DPIO

DBA-1 and MMA

respectively.
