英文摘要The hydrophobically modified polyelectrolyte was synthesized using precipitation polymerization of acrylic acid and 3-[tris(trimethylsilyloxy)silyl]propyl methacrylate (tmspma) in various molar ratios in supercritical carbon dioxide. ft-ir, (1)h nmr, capillary viscometry, rotational viscometer, transmission electron microscopy and fluorescence spectroscopy were used to characterize this copolymer. the viscosity of the copolymers showed a strong dependence on ph with a maximum at ph=5.5. associating morphologies of the copolymer were observed by tem. associating morphologies of poly(aa-co-tmspma) solution changed from a global structure to a shell-core structure with increasing hydrophobic levels. a solution of sample pat4 with a shell-core structure had the largest viscosity value. in addition, the critical micelle concentration of copolymer solution, cmc, was determined from the relative viscosity. the critical micelle concentration was further confirmed by fluorescence spectroscopy using 1-pyrenemethylamine hydrochloride, pymea center dot hcl, as a cationic fluorescent probe. the cmc was determined from the intensity ratios, the first to the third emission peaks i (1)/i (3), and the excimer to monomer i (e)/i (m) ratio of the pyrene probe as a function of concentration.
