抄録

The graft copolymerization of methyl methacrylate onto chitosan was carried out, and the following results were obtained.<br>1) In the case of the non-catalytic photo-induced method, an induction period was observed and the polymerization proceeded mainly by the photolysis of amino groups.<br>2) In case of the photosensitized method, the grafting activity of azobisisobutylonitrile was higher than that of ph2 CO.<br>3) In the initiator method, the grafting activity of ammonium persulfate was higher than that of H2O2.<br>The degree of grafting and the apparent number of grafted chains generally decreased in the following order; the initiator method>the photo-induced method without catalyst>the photoinduced method with photosensitizer.<br>As for the photo-induced graft copolymerization of binary monomers (AN-MMA and AN-St) in the presence of chirosan, the monomer reactivity ratios of the graft and the ungrafted copolymer almost coincided with the values of the literature obtained in homogeneous system.
