| 摘 要： | A kinetic study on the photopolymerization of methyl methacrylate (MMA) with benzophenone(BP)/triethylamine (TEA)/mercaptan systems as initiator has been carried out in the presence of oxygen.It was found that both aliphatic and aromatic thiols promote the photooxidation process, leadingto obvious decrease in induction period of photopolymerization. The rate-aereleration of aromaticthiols is more effective than that of aliphatic ones, such as p-toluene thiol used as additive increasesthe relative quantum yield φ_(O2)/φ_(N2) to 1.8.
