The paper deals with the surface modification of a heterogeneous cation-exchange membrane with the application for electrodialysis, electrodeionisation, and electrolysis. CM(H)-PP (cation exchange membrane based on polyethylene binder) membrane was covalently attached with poly(divinylbenzene-co-4-vinylbenzylchloride). We have achieved better properties than commercially available heterogeneous ion-exchange membranes in the field of chemical, electrochemical properties by the formation of layer. Ion-exchange capacity was determined with maximum value 2.99 meq g−1 dry matter, area resistance 9.9 Ω cm2 and specific resistance 149 Ω cm, permselectivity 93.4%. [ABSTRACT FROM AUTHOR]

The paper deals with a novel flame retardant and its application in waterborne coatings. The flame retardant was synthesized from hexachloro-cyclo-triphosphazene by nucleophilic substitution with allylamine. Functionalized emulsion copolymers bearing in the structure hexaallylamino-cyclo-triphosphazene were prepared by the semicontinuous emulsion polymerization. The latexes were used as the main component of transparent coating systems cured by melamine formaldehyde resin. The incorporation hexaallylamino-cyclo-triphosphazene did not affect transparency, flexibility, and toughness of resulting coatings and increased their flame stability in terms of the amount of smoke release and maximum average rate of heat emission indicating a slower flame spread during the material combustion.

Epoxy resins can exhibit some excellent properties. The basic principle of curing epoxy resins with a curing agent containing multiple amino groups is the crosslinking reaction between active hydrogen atoms from the curing agent and the oxirane groups in the epoxy resin structure. This study deals with the synthesis of derivative of hexachloro-cyclo-triphosphazene (HCCTP) using curing of epoxy resins. The study of our interest is nucleophilic substitution of HCCTP usingN-[3-(trimethoxysilyl)propyl]ethylene diamine. The prepared derivative offers two potential advantages over conventional curing systems, namely improving properties during burning. [ABSTRACT FROM AUTHOR]
