通过基团转移聚合（GTP）合成了甲基丙烯酸（MAA）、甲基丙烯酸2-（二甲氨基）乙酯（DMAEMA）、甲基丙烯酸甲酯（MMA）和甲基丙烯酸2-苯乙酯（PEMA）的水溶性、低多分散性、低分子量无规、AB二嵌段和ABC三嵌段聚合物。报告了这些聚两性电解质的等电点、滴定行为和溶解度曲线。光散射研究表明，由于 MMA 疏水性嵌段的存在，三嵌段形成胶束。荧光研究表明，三嵌段共聚物与芘的结合比相应的无规三元共聚物更强。
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.
