Description

Photo-induced graft polymerization of methyl methacrylate onto mesyl cellulose has been studied with and without azobisisobutylonitrile (AIBN). The graft polymerization in the absence of AIBN proceeds mainly via the photolysis of mesyl cellulose. Since using a quartz tube may result in the scission of cellulose molecule, the grafting also occurs at the end of cellulose. The graft polymerization in the presence of AIBN takes place not only by the photolysis of mesyl cellulose but also by the chain transfer of homo polymer to the trank polymer. The graft polymerization with AIBN starts at lower temperature than without AIBN. The termination is caused by the reaction between cellulose radicals and growing polymer radicals. As a small amount of dimethylformamide solution is added in the polymerization system, the affinity between mesyl cellulose and monomer increases, and owing to this reason the degree of grafting and the number of grafted chains increase. The photolysis of mesyl cellulose was also investigated by the I. R. spectra.
