Abstract

Using the Mayo and the Clay‐Gilbert method, the transfer rate coefficient of α‐thioglycerol (TG) was determined at 50°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.

## Abstract The reverse atom transfer radical polymerization of methyl methacrylate was investigated in different solvents: xylene, __N,N__‐dimethylformamide, and pyridine. The polymerizations were uncontrolled, using 2,2′‐bipyridine as a ligand in xylene and pyridine because the catalyst (CuBr~2~/
