Abstract:A phosphorus-containing monomer (10-oxo-10-hydro-9-oxa-10 lambda(5)-phosphaphenanthrene-10-yl)-methyl acrylate (M-1) 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 H-1 NMR measurements. The reactivity ratios for free-radical of the monomer (M-1) and styrene (M-2) were studied. The calculated results are as follows: r(1) = 0.225, r(2) = 0.503; Q(1) = 0.413, e(1) = 0.476; azeotropic point = 0.37. TGA and DTG curves indicated that M-1 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.
