Vinyl polymerization, 311. Synthesis and polymerization of 2-bromoethoxyphenoxyphosphoryl methacrylate

2-Bromoethoxyphenoxyphosphoryl methacrylate ( 5 ) was synthesized by the reaction of 2-bromoethyl phenylchlorophosphonate ( 3 ) with silver methacrylate and then polymerized by a radical initiator. The resulting polymer was soluble in DMF, but insoluble in other organic solvents. The hydrolysis of the polymer with sulfuric acid led to the corresponding poly(methacrylic acid) with a molecular weight of M_n=4,4·10⁵ (P_n=5,1·10³). 5 was copolymerized with acrylonitrile and the monomer reactivity ratio was determined: r₁ = 2,20, r₂=0,27.
