In order to adapt the properties of living materials to their
biological functions, nature has developed unique polyelectrolytes
with outstanding physical, chemical and mechanical behavior. Namely
polyampholytes can be suitable substances to model protein folding
phenomenon and enzymatic activity most of biological macromolecules
due to the presence of acidic and basic groups. The ability of
linear and crosslinked amphoteric macromolecules to adopt globular,
coil, helix and stretched conformations and to demonstrate
coil-globule, helix-coil phase transitions, and sol-gel, collapsed
expanded volume changes in relation to internal (nature and
distribution of acid and base substituents, copolymer composition,
hydrophobicity etc. ) and external (pH, temperature, ionic strength
of the solution, thermodynamic quality of solvents etc. ) factors
is very important and constantly attracts the attention of
theorists and experimentalists because the hierarchy of amphoteric
macromolecules can repeat, more or less, the structural
organization of proteins. That is why polyampholytes fall within
eyeshot of several disciplines, at least polymer chemistry and
physics, molecular biology, colloid chemistry, coordination
chemistry and catalysis. The main purpose of this monograph is to
bridge the gap between synthetic and natural polymers and to show a
closer relationship between two fascinating worlds. The first
chapter of the book acquaints the readers with synthetic strategy
of "annealed," "quenched" and "zwitterionic" polyampholytes.
Radical copolymerization, chemical modification and
radiation-chemical polymerization methods are thoroughly
considered. Kinetics and mechanism of formation of random,
alternating, graft, di-block or tri-block sequences is discussed.
The second chapter deals with behavior of polyampholytes in
solutions."
