We report an investigation into the thermally induced catalytic chain transfer polymerization (CCTP) using bis[(difluoroboryl)dimethylglyoximato] cobalt(II) (CoBF) as a chain transfer agent in three different flow reactors: (1) a cascade of continuous stirred-tank reactors (CSTRs), (2) a simple tubular flow reactor, and (3) a Corning Advanced Flow Reactor (AFR). Systematic variations in monomer type, temperature, and stirring rate were employed to investigate their effects on the polymerization process. In the CSTR cascade, higher polymerization rates and conversions were observed without compromising reaction control. Comparative analyses between the flow systems and conventional batch reactions were performed to assess the performance of CoBF under these different reaction conditions. All reactor designs proved successful in carrying out CCTP, and this chemistry is well-suited to continuous production under different flow conditions. The applicability of the reaction system was further verified with successful CCTP of glycidyl methacrylate, and the reproducibility was confirmed by using online continuous GPC.
