PHOSPHORUS-CONTAINING COPOLYMER PREPARATION METHOD Russian patent published in 2006 - IPC C08F212/08 

FIELD: polymer production.

SUBSTANCE: phosphorus-containing copolymers are prepared via copolymerization of styrene of methyl methacrylate with phosphorus-containing monomers in bulk or organic solvent medium at 50-80^°C in presence of free radical initiators, polymerization method being characterized by that, in order to obtain uninflammable copolymers with improved properties, phosphorus-containing monomers of formula CH₃-P(=O)R-OCH₂CH₂O-CO-C(CH₃)=CH₂, where R represents hydroxyl, phenyl, phenoxy or alkoxy, are utilized. Use of methacryloyl-ethylene glycol esters of a variety of methylphosphonic acids as monomers allows uninflammable copolymers to be prepared having linear rather than cross-linked structures typical of known copolymers.

EFFECT: increased solubility of polymers thus prepared in organic solvents.
