摘　　要：利用凝胶层析法作为明胶接枝丙烯酰胺产物的分析手段，研究了不同分子量及其分布、不同粘度的产物对胶片照相性能的影响，发现该接枝产物对胶片有明显的增黑效果。Inthis paper the gelatin acrylamide graft copolymers were separated by gel filtration chromatography.The molecular weight,the molecular weight distribution and viscosity of the products were investigated,their influence on photographic film were also tested,it was found that the gelatin acrylamide graft copolymers improve the covering power obviously.

关 键 词：明胶-丙烯酰胺接枝共聚物 凝胶层析 分子量分布 照相性能
