Photoinduced graft copolymerization: X—Graft copolymerization of methyl methacrylate onto wool using isoquinoline-sulphur dioxide charge-transfer complex as the initiator

The photoinduced graft copolymerization of methyl methacrylate onto wool fibre was investigated using an isoquinoline-sulphur dioxide charge-transfer complex as the initiator. The percentage of graft yield increases with increasing concentration of the monomer and the initiator. The reaction was carried out at three different concentrations and the overall activation energy was computed. The kinetic data and other evidence indicate that the overall polymerization takes place by a radical mechanism. A suitable kinetic scheme has been suggested.
