Abstract

A phosphorus-containing monomer (10-oxo-10-hydro-9-oxa-10λ5-phospha-phenanthrene-10-yl)-methyl acrylate (M1) 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 (M2) 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 M1 is a potential flame retarding monomer for styrenic polymers.
