Abstract The graft copolymerization of methyl methacrylate onto nylon 6 using metal complexes of Mn 3+ , Co 3+ , and Fe 3+ as initiators was studied. The rate of polymerization, R p , increased with increasing complex concentrations in the initial stages; but it decreased upon further increase of complex concentrations. With increasing monomer concentrations, the rate of polymerization increased progressively. The graft yield increased with increaing temperature within the range 60–75°C. A suitable kinetic scheme is presented and rate equations are derived.
