| 英文摘要 | Poly(N,N-dimethylacrylamide)(PDMA) contaiing perfluoro-octyl pendent groups was prepared by solution polymerization of N,N-dimethylacrylamide in benzene with 0.16-1.25 mol% 2-(N-ethylperfluoro-octane sulfonamido) ethyl acrylate (FX-13^R) or 2-(N-ethylperfluoro-octane sulfonamido) ethyl methacrylate (FX-14^R). The copolymer intrinsic viscosity strongly decreases with increasing comonomer contert due to intramolecular association. However,the Huggins constant increases more than 40-fold with increasing comonomer contert, indicating that intermolecular association increases with increasing comonomer contert. Strong Brookfiedldviscosity enhancements are observed above a critical copolymer concentration varying between 0.5 and 2.0wt% depending on comonomer type and content. Some of the copolymers show pseudoplastic behaviour whereas others show shear-thickening or both types of behaviour. These observations are consistent with competing inter-and intramolecular micellar association. Fluorescence studies using a perfluorocarbonsubstituted pyrene as a probe indicate the formation of hydrophobic microdomanins formed by the association of perfluorocarbon groups. |
