The activity of diallylamido-bis(diethylamido)guanidinium chloride in radical polymerization and copolymerization with vinyl monomers giving rise to random copolymers has been studied. A lower activity of diallylamido-bis(diethylamido)guanidinium chloride than that of vinyl monomers has been demonstrated. It has been shown that this monomer readily copolymerizes with sulfur dioxide and alternating copolymers of equimolar composition are formed regardless of the comonomer ratio in the initial mixture and the reaction conditions (the nature of solvent and initiator, temperature, and conversion). The structure of polymers has been studied by 13C NMR spectroscopy.

The copolymerization of N,N-diallyl-N,N-dimethylammonium chloride and fumaric acid under conditions of radical initiation is studied. The reaction yields copolymers that exhibit a random distribution of comonomer units in the macrochain. Fumaric acid is highly active in the copolymerization of the above system. A significant effect on the relative activity of the comonomers is exerted by the type of solvent. The kinetics of the copolymerization is studied; the structuring of the copolymers is determined.

Copolymers of N,N-diallyl-N,N-dimethylammonium chloride with sulfur dioxide, maleic acid, and vinylacetate were synthesized by radical polymerization. Their biological properties were studied. It was established that the obtained copolymers belonged to class IV low-toxicity substances and exhibited pronounced antimicrobial activity with respect to some bacterial and fungal species.

Immobilization of drugs on macromolecules of copolymer N,N-diallyl-N,N-dimethylammonium chloride with sulfur dioxide using ion exchange technique was investigated. Ways of producing polymer-drug conjugates of preset compositions were developed. Their structure was found by NMR and IR spectroscopy.

The free-radical copolymerization of N,N-diallyl-N,N-dimethylammonium chloride with vinyl acetate in DMSO, methanol, and a methanol-water (70: 30, mol %) mixture proceeds to yield statistical copolymers. The nature of solvents significantly affects the reactivity ratios of the comonomers. N,N-Diallyl-N,N-dimethylammonium chloride shows a higher reactivity than vinyl acetate. The kinetic features of the processes have been investigated, and the structure and properties of the copolymers have been studied.

Vinyl ether of cholesterol has been polymerized through the free-radical mechanism with a yield of up to 30% to obtain optically active soluble oligomers. By the example of acrylonitrile, N-vinylpyrrolidone, ethylene glycol vinyl glycidyl ether, and N-vinyl-4,5,6,7-tetrahydroindole, it has been established that optically active copolymers of cholesterol may be synthesized.

Vinyl 2-hydroxyethyl sulfide (VHES) homopolymer and the homopolymer and vinyl 2-hydroxyethyl sulfide-acryl amide copolymer cross-linked by bisacrylamide were prepared by radical polymerization. The sorption of Au(III), Ag(I), Pd(II), Pt(IV), Hg(II), Pb(II), Fe(III), Ni(II), Cu(II) on these polymers under the static conditions was studied in relation to the solution pH. The polymers are highly selective and efficient sorbents for Au(III), Ag(I) and Hg(II).
