Optimized conditions for grafting reaction of poly (methyl methacrylate) onto talc filler

In this study, poly(methyl methacrylate) (PMMA) grafted onto talc was produced using free radical polymerization. Hydrogen peroxide (H202) and ferrous ions (Fe2+) were used as a redox initiator/co-catalyst system. Grafting copolymerization was carried out under nitrogen atmospheric since it is known...
