Abstract�� Butyl acrylate(BA) and acrylonitrile(AN)were grafted by copolymeri zation onto photographic gelatin. The effects of the feeding method of monomers (BA and AN) on the reaction were studied in detail.The grafted samples were examined by ninhydrin reaction, IR spect roscopic method, DSC technique, amino acid determination and nitrogen element analysis. All of these measurements offer evidences to the forma tion of grafting pBA and pAN onto gelatin.
