Photoinduced graft copolymerization: XII—Graft copolymerization of methyl methacrylate onto wool using peroxydiphosphate as the photoinitiator

Abstract

The photoinduced graft copolymerization of methyl methacrylate onto wool fibers was investigated using peroxydiphosphate as the initiator. Up to a certain concentration of the monomer and the initiator the graft yield increased beyond that concentration a decreasing trend was observed. The reaction was carried out at four different temperatures and the energy of activation was evaluated. The kinetic data and other evidence indicate that the overall polymerization takes place by a radical mechanism. A suitable reaction scheme has been proposed.
