A new organofunctional cyclophosphazene monomer, Methacryloylethylenedioxy pentachlorocyclotriphosphazeneN3P3CI5OCH2CH2OC2O CCH3CH2 I has been prepared from 2-hydroxyethyl methacrylate and hexachlorocyclotriphosphazene. Radical initiated homopolymerization of I and copolymerization of I with methyl methacrylate proceeds readily. The new flame retardent polymers have been characterized by elemental analysis, NMR spectroscopy, gel permeation chromatography, membrane osmometry and TGA. Reactivity ratios and Alfrey-Price parameters for the methyl methacrylate copolymerization show a significant effect of the phosphazene on the olefin reactivity.
