Book excerpt: This volume deals with chemistry of polyelectrolytes, namely biocide guanidine containing polymers, discussing both synthesis of new guanidine containing monomers of diallyl and acrylic nature and their structure and investigation of their radical (co)polymerization and properties of new (co)polymers. The first parts of the book describe radical polymerization of these monomers and their co-polymerization with diallyldialkylammonium derivatives, features of their kinetic behavior in these processes (for example, polymerization rates, reactivity ratios) The sections on phycal chemical methods (IR, NMR, DSC ect.) are especially important for studying of structure and properties of synthesized monomer and polymer compounds. The book is finely illustrated with about hundred original figures, schemes and tables including kinetics, NMR, IR spectroscopy, biocide and other data.
