Abstract (en)
[origin: WO2021254993A1] The invention relates to: a process for producing oxa phosphaphenanthrene oxide acrylate monomers by phospha-Michael addition to acrylates, in which process oxa phosphaphenanthrene oxide is reacted with an α,ω-alkyldiol diacrylate in a molar ratio of 1:1.5 to 1:10 in the presence of a base and a polymerisation inhibitor at temperatures of 70 to 120°C and unreacted α,ω-alkyldiol diacrylate is removed; monomers obtainable by means of the process and the use thereof for producing flameproof thermoplastic (meth)acrylate polymers and a process for producing flameproof thermoplastic (meth)acrylate polymers using the monomers; polymers obtainable thereby and the use thereof for producing transparent films and panels.
