Solution Properties of Cationic Polyacrylamide Modified with Fluorinated Methacrylate

Abstract:

Cationic polyacrylamides modified with fluorinated methacrylate (FPAM) were prepared with acrylamide, dodecafluoroheptyl methacrylate (DFM) and methacryloxyethyl trimethylammonium chloride by free radical micellar copolymerization. The solution properties of FPAM were investigated. The results show that there are strong hydrophobic associations in the FPAM aqueous solution. The intrinsic viscosity decreases and Huggins constant increases with the increase of DFM content. The apparent viscosity of FPAM solution increases with increasing the FPAM concentration both in water and salt solution. There are maximum values of the apparent viscosity of FPAM with addition of sodium chloride, CTAB and sodium dodecyl sulfate (SDS), respectively. Additionally, the FPAM has higher surface activity in salt solution than in water.
