Summary:

This book comprehensively reviews the synthesis, characterization and application aspects of linear and crosslinkedsynthetic polyampholytes - simple model of biopolymers -starting from the 1950's. The synthetic strategy of "annealed,""quenched" and "zwitterionic" polyampholytes, the properties ofpolyampholytes in solutions and in gel state are considered. Thecomplexation ability of polyampholytes with respect to transitionmetal ions, ionic surfactants, dyes and organic probespolyelectrolytes, proteins and colloid particles is discussed.Stimuli-sensitive behavior of various amphoteric gel and membranesystems demonstrating rhythmically phenomenon similar to that of heartbeat, deformation, oscillation or self-oscillation phenomenastimulated by temperature, pH and electric field are illustrated.Catalytic properties of synthetic polyampholytes simulating thefunction of enzymes are also considered.
