Summary Methylmethacrylate and styrene were polymerized with Co(acac)3-AlEt2 Br catalyst system in benzene at 40°C. Rate of polymerization is linear to monomer concentrations. Maximum percent conversion of polymer was obtained when Al/Co⩾2 with styrene and Al/Co⩾3 with methylmethacrylate. With increase in aging time catalytic activity decreases. Activation energy was found to be 60 KJ mol−1. with styrene and 40 KJ mol−1. with methylmethacrylate.
