Preparation of Novel Derivatives Containing Bi-Perfluorooctane-Sulfonamide Groups and Their Surface Properties on Paper

Novel derivatives containing bi-perfluorooctane-sulfonamide group were designed and synthesized.The 19FNMR,FTIR were used to characterize derivatives structures.The compounds were applied to paper for oil-repellency.The results show that treated paper had excellent oil-repellency at very low concentration of bi-perfluorooctane-sulfonamide derivatives.When novel compounds,polyvinyl alcohol(PVA)and oxidized starch were applied together as coat sizing,the oxidized starch and PVA did not affect the oil repellency properties of paper.
