Self-Crosslinking Acrylic Latexes with Copolymerized Flame Retardant Based on Halogenophosphazene Derivative

Abstract

In this study the synthesis of a novel flame retardant based on halogenophosphazene derivative and its application in waterborne coatings based on self-crosslinking latexes was investigated. Hexaallylamino-cyclo-triphosphazene was synthesized by nucleophilic substitution of hexachloro-cyclo-triphosphazene with allyl amine. Latexes of functionalized core-shell particles bearing in the structure hexaallylamino-cyclo-triphosphazene molecules were prepared by emulsion polymerization of methyl methacrylate, butyl acrylate and methacrylic acid as main monomers.
