摘要
研究了丙烯酸丁酯（ＢＡ）和丙烯腈（ＡＮ）与明胶的接枝共聚物Ｇｅｌ－ｇ－ｐ（ＢＡ－ＡＮ）乳液对胶片照相性能和涂布性能的影响。实验结果表明，共聚物乳液中残余的引发剂过硫酸钾（ＫＰＳ）使胶片的感光度明显降低，并产生严重的黄色灰雾；残余单体ＡＮ在一定程度上影响Ｂ、Ｇ、Ｒ层的γ、Ｓ值（提高Ｂ、Ｒ层的Ｓ，降低Ｒ层的γ）；残余的单体ＢＡ造成胶片护膜层表面不均匀。采用吸附树脂分离纯化后，能有效地去除残留在共聚物乳液中的有害物质；纯化后的乳液对胶片的照相性能没有不良影响。
As the results showed,the residue of inititor potassium persulfate KPS in the graft copolymer emulsion caused the photosensitivity of the film to decrease greatly and heavy yellow fog;the residue of monomer AN acrylonitrile to some extent influences the γ、S of the B、G、R layers;the residue of monomer BA butyl acrylate gives rise to some spots on the surface of the protecting layer.After purified with absorbent resin,the graft copolymer emulsion has no harmful effects on the photographic properties of film.
