The FNMR, 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.展开更多
