Abstract: Method for manufacturing oxaphosphaphenantrene oxide acrylate monomers by Phospha-Michael addition to acrylates, which comprises reacting oxaphosphaphenantrene oxide with an α,ω-alkyl diol diacrylate in a molar ratio of 1:1.5 to 1:10 in the presence of a base and a polymerisation inhibitor at temperatures from 70 to 120° C. and unreacted α,ω-alkyl diol diacrylate is separated off, monomers obtainable with the method and their use for manufacturing flame retardant thermoplastic (meth)acrylate polymers and method for manufacturing flame retardant thermoplastic (meth)acrylate polymers with the monomers, polymers obtainable in this way and their use for manufacturing transparent films and panels.
