This quantity bargains with chemistry of polyelectrolytes, particularly biocide guanidine containing polymers, discussing either synthesis of latest guanidine containing monomers of diallyl and acrylic nature and their constitution and research in their radical (co)polymerization and houses of latest (co)polymers. the 1st components of the booklet describe radical polymerization of those monomers and their co-polymerization with diallyldialkylammonium derivatives, good points in their kinetic habit in those methods (for instance, polymerization premiums, reactivity ratios) The sections on phycal chemical equipment (IR, NMR, DSC ect.) are specifically vital for learning of constitution and houses of synthesized monomer and polymer compounds. The publication is finely illustrated with approximately hundred unique figures, schemes and tables together with kinetics, NMR, IR spectroscopy, biocide and different facts.

2. Conformational state of propagating chains under radical polymerization of aery/ate- and methacrylate guanidines The very important characteristic of physical-chemical behavior of polyelectrolytes in solution is conformational state which depends on a great number of factors including nature of solvents, polymer ionization degree, solution ion force, etc. Investigation of conformational behavior of macromolecules containing charged fragments in the chain causes significant interest of researches not only from theoretical point of view, but also from positions of possible application of such polymers for solution of medical-biological, ecological and other problems [115).
Work [111, 112]. First of all we shall consider what differences are characteristic for heterogeneous polymerization in comparison with homogeneous. As a rule they are the following: the increase of reaction order by initiator from 0,5 up to 1,0; the sharp rise of polymerization rate with the rise of conversion (auto-catalytic process); the decrease of termination rate constant and the increase of molecular masses of resulted polymers. The increase of reaction order by initiator from 0,5 up to 1,0 is observed as under heterogeneous polymerization, so at the stage of high conversions under homogeneous polymerization in the region of so-called "gel-effect" that is connected as a rule with the decrease of k 1 caused by the reduction of probability of meeting of polymer radicals occluded in balls.
