Abstrakti

New hydrophilic polyampholytes have been synthesized by copolymn. of 1-vinylimidazole with sodium salts of acrylic and methacrylic acids. Copolymn. reactivity ratios of the monomers are equal to: 0.54 ± 0.06 and 1.3 ± 0.3 for 1-vinylimidazole-sodium acrylate, 0.23 ± 0.01 and 2.6 ± 0.2 for 1-vinylimidazole-sodium methacrylate systems, correspondingly. Isoelec. point of the copolymers changes continuously from 2.8 to 6.7 with increasing the 1-vinylimidazole content in contrast to polyampholytes with amino instead of imidazole side groups, whose isoelec. point changes discontinuously with changing compn. Static and dynamic light scattering data point to tendency of polyampholyte macromols. to aggregation, even at pH values far from isoelec. point. [on SciFinder(R)]
