| Abstract Butyl acrylate was graft copolymerized onto gelatin using ceric ammonium nitrate as redox initiator.A serious of grafted products with various gelatin-to-butyl acrylate ratios were prepared.The mol wt.of the grafted side chains and the number of grafting sites were measured. The possible grafting sites on gelatin macromolecules were pointed out through amino acid analysis.The electron micrograph and DSC analysis showed that the grafted chain (PBA) and backbone gelatin were in separated phases.The graft copolymer was used in the receiving layer of the dye transfer blank film,and the photographic,dye transfer printing,and some physico-mechanical properties were studied with satisfactory results. |
