Sorption of Noble Metal Compounds by Cross-Linked Copolymer of 1-Vinyl-1,2,4-Triazole with Acrylic Acid

Sorption properties with respect to noble metal compounds were examined for a new divinyl benzene cross-linked nitrogen-containing heterocyclic copolymer of 1-vinyl-1,2,4-triazole with acrylic acid. The sorption recovery of chloride complexes of Au(III), Pt(IV), Pd(II), and Ag(I), as well as of silver nitrate from acidic solutions was examined in relation to the nature and concentration of acids and the contact time between the phases.

Modification of polyvinyl chloride with Na(K) salts of 1,2,4-triazole and 1,2,3-benzotriazole

The possibility of polyvinyl chloride modification by nucleophilic substitution of chlorine with sodium and potassium salts of 1,2,4-triazole and 1,2,3-benzotriazole in dimethylformamide at 40-80°C was examined.

Copolymerization of 1-(Vinyloxyalkoxy)-2,3-epoxypropanes with Vinyl Chloride

Binary radical polymerization of vinyl chloride with 1-(vinyloxyalkoxy)-2,3-epoxypropanes in acetone and dimethyl sulfoxide was studied. The copolymerization constants and the microstructural parameters of the resulting copolymers were calculated.

PROTON-CONDUCTING MEMBRANES BASED ON COPOLYMER COMPOSITES

Copolymers of 1-vinyl-1,2,4-triazole with methyl methacrylate and fluoroalkylmethacrylates have been modified with phosphorus- and silicon-molybdenum heteropolyacids as well as copolymer of ethylene glycol vinyl glycidyl ether with N-phenylmaleimide to furnish new composite materials. The elastic films obtained show proton conductivity of about 10−3–10−1 S/cm (after doping with orthophosphoric acid). They are promising candidates for the design of proton-conductive membranes

Properties and Application Prospects of 1-(Vinyloxyalkoxy)propylene 2,3-Oxide Copolymers

Thermal stability, impact strength, folding resistance, and adhesion were studied for copolymers of vinyl chloride and 1-(vinyloxyalkoxy)propylene 2,3-oxides prepared in acetone and dimethyl sulfoxide.

Copolymerization of vinyl chloride with 1-(vinyloxyalkoxy)propylene oxides-2,3: Solvophobic effects of solvents

The influence of solvophobic effects of aprotic solvents on the reactivity of 1-(vinyloxyalkoxy)propylene oxides-2,3 in free-radical copolymerization with vinyl chloride has been studied by dynamic light scattering. It has been shown that the association of copolymer macromolecules in aprotic solvents results in the reduced reactivity of 1-(vinyloxyalcoxy)propylene oxides-2,3. This effect can be explained by a decrease in their local concentration in the vicinity of the reaction center.
