摘要：

Tert.-dodencanethiol can initiate the copolymerization of methyl methacrylate (MMA) and styrene (St) near room temperature. Experimental results indicate that tert.-dodencanethiol (RSH) influences the initial rate of copolymerization (R(p)) only insignificantly, when its concentration ranges from 4.3 x 10(-4) to 2.7 x 10(-2) mol/1; R(p) increases as [MMA] in monomer composition is increased; the activation energy of the copolymerization at 30-degrees-C approximately 45-degrees-C is determined to be 56.4kJ / mol; the fact that the molecular weight of the copolymer decreases as [RSH] is increased indicated that thiol acts in the reaction not only as an initiator but also as a chaintransfer agent.
