摘　　要：A phosphorus-containing monomer （lO-oxo-10-hydro-9-oxa-10λ^5-phosphaphenanthrene-10-yl）-methyl acrylate （MD was copolymerized with styrene to give a potential flame retardant copolymer of high thermal stability. The structures of monomer and copolymer were characterized by FT-IR and ^1H NMR measurements. The reactivity ratios for free-radical of the monomer （M1） and styrene （Mz） were studied. The calculated results are as follows： r1 = 0.225, r2 = 0.503; Q1 = 0.413, e1 = 0.476; azeotropic point = 0.37. TGA and DTG curves indicated that Ml is a potential flame retarding monomer for styrenic polymers. C 2009 Yu Bin Zheng. Published by Elsevier B.V. on behalf of Chinese Chemical Society.
