Hydrolytically stable and polymerizable acrylic phosphonic acid

摘要

Hydrolysis-stable and polymerizable acrylated mono- and diphosphonic acids, which are 2-(dihydroxyphosphoryl-oxa-alkyl)-acrylic acids or esters or corresponding bis compounds, and their stereoisomers and mixtures are new. Hydrolysis-stable and polymerizable acrylated mono- and diphosphonic acids, which are 2-(dihydroxyphosphoryl-oxa-alkyl)-acrylic acids or esters or corresponding bis compounds of formula (I), and their stereoisomers and mixtures are new; R1 = H, 1-10 carbon (C) alkyl or 6-10C aryl; R2 = H, F, 1-5C alkyl or phenyl; R3 = 1-8C alkylene or phenylene or is absent; Y = oxygen (-O-), sulfur (-S-), 1-8 C alkylene or is absent; n = 1 or 2; X = H, F, 1-5C alkyl or 6-12C aryl if n = 1; X = 1-10C alkylene, 6-10C arylene, 7-20C arylenealkylene or is absent if n = 2; The individual alkyl, aryl, alkylene, arylene, phenyl, phenylene and arylenealkylene groups may have substituent(s). Independent claims are also included for (a) (co)polymers obtained by (co)polymerization of (I); and (b) the preparation of (I).
