摘要: Fluorocarbon (R-F) Or hydrocarbon (R-H) end-capped PEG macromonomers were prepared by coupling method. Several factors that affect the synthesis were studied and optimum condition was obtained. The critical micelle concentrations (CMC) of these macromonomers were determined by fluorescence method. A new type of fluorocarbon-containing hydrophobically modified alkali swellable/soluble copolymers were obtained by copolymerization of R-F or R-H alkyl end-capped PEG macromonomers with acrylic acid in organic solvent. The preliminary researches on viscosity property of these copolymer solutions were conducted under different conditions, such as various macromonomer content in the copolymer, polymer concentration, shear rate, pH value and temperature. All the results proved that there existed a very strong hydrophobic association among hydrophobes in these copolymer solutions.
