明胶上接枝丙烯酸丁酯的研究 Ⅲ.接枝产物的表征及其在染印法空白片上的应用初探

摘要明胶上接枝丙烯酸丁酯的反应是在 Ce~(4+)存在下进行的。不同的明胶与丙烯酸丁酯配比,可获得一系列不同的接枝产物,此接枝产物的存在由红外光谱和茚三酮试验所证实.测定了接枝侧链的分子量和平均接枝点数目.根据氨基酸分析结果推测了接枝点的可能位置。电子显微照片和 DSC 均表明明胶和聚丙烯酸丁酯侧链处于相分离状态.将此接枝共聚物用于彩色电影染印法空白片的接受层中,其感光性能、染印性能以及一些物理-机械性能均获得较为满意的效果.

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.
