摘要：

Using the Mayo and the Clay-Gilbert method, the transfer rate coefficient of alpha-thioglycerol (TG) was determined at 50 degrees C for the polymerization of methyl methacrylate (MMA) in a 3 mol.L-1 tetrahydrofuran solution using different amounts of 2,2'-azoisobutyronitrile (AIBN) as initiator. The transfer rate coefficient was found to be independent of the initiator concentration and higher by a factor of 1.6 when obtained according to the Clay-Gilbert method compared to the Mayo method.
