摘要：

Water-soluble, low-polydispersity, low-molecular-weight random, AB diblock, and ABC triblock polymers of methacrylic acid (MAA), 2-(dimethylamino)ethyl methacrylate (DMAEMA), methyl methacrylate (MMA) and 2-phenylethyl methacrylate (PEMA) were synthesized by group transfer polymerization (GTP). The isoelectric points, titration behavior, and solubility curves of these polyampholytes are reported. Light scattering studies revealed that the triblocks form micelles as a result of the presence of the MMA hydrophobic block. A fluorescence study demonstrated that the triblock copolymers associate more strongly with pyrene than do the corresponding random terpolymers.
