説明
The photo-induced graft polymerization onto 2, 3-dialdehyde cellulose was carried out in a quartz tube. The initial rate of grafting decreased in the order of methyl acrylate, methyl methacrylate, vinyl acetate, acrylonitrile and styrene, and the graft efficiency was 70-98% except for a quite low value of vinyl acetate. The degree of grafting in the graft polymerization of styrene and acrylonitrile increased with the monomer concentration. The degree of grafting and the apparent number of grafted chains increased and grafted chain length decreased, with increasing the carbonyl content in cellulose. The larger apparent number of grafted acrylonitrile chains obtained in a quartz tube than that obtained in a pyrex tube showed that the graft polymerization in a pyrex tube proceeds mainly via the photolyses of carbonyl groups in cellulose by the light longer than 300 nm. On irradiation with the light of 253 nm in a quartz tube, however, grafting onto the end group, due to the chain scission of cellulose molecule, concurrently occured. Termination proceeds by the coupling between the growing polymer radical and the cellulose radical.
