Abstract
The graft copolymerization of methyl methacrylate onto nylon 6 initiated by peroxydiphosphate coupled with bivalent metals like Fe(II) and Mn(II) is studied. The rate of grafting increases progressively with increasing the peroxydiphosphate, monomer, and acid concentrations. The graft yield also increases with increasing the concentrations of Fe(II) and Mn(II) from 5.0 × 10−4 to 60 × 10−4 M. The effect of the addition of some solvents and temperature on graft yield is also studied. Both systems were investigated at identical conditions. A larger percentage of grafting is observed for Mn(n) than for Fe(II). A suitable kinetic scheme is developed and rate equations are derived.
