Abstract:
A process for producing a water-soluble, hydrolysis-stable, polymerizable polymer, comprising a) a step of copolymerizing a mixture comprising (i) a first copolymerizable monomer comprising at least one optionally protected carboxylic acid group and a first polymerizable organic moiety, and (ii) a second copolymerizable monomer comprising one or more optionally protected primary and/or secondary amino groups and a second polymerizable organic moiety, for obtaining an amino group containing copolymer; b) a step of coupling to the amino group containing copolymer a compound having a polymerizable moiety and a functional group reactive with an amino group of repeating units derived from the second copolymerizable monomer in the amino group containing copolymer obtained in the first step wherein the optionally protected amino group is deprotected, so that polymerizable pendant groups are linked to the backbone by hydrolysis-stable linking groups, and, optionally, a step of deprotecting the protected carboxylic acid group after step (a) or step (b), for obtaining a polymerizable polymer.

Claim (Index 7):
The polymerizable polymer according to  claim 1 , wherein the second copolymerizable monomer is represented by the general formula (2): wherein R 3  is a hydrogen atom or a straight chain or branched C 1-6  alkyl group which may be substituted by a \u2014COOZ\u2032 group; X is a protected amino group or a hydrocarbon group having 1 to 20 carbon atoms, which is substituted with an amino group which may carry a protecting group, wherein the hydrocarbon group may contain 1 to 6 heteroatoms, which heteroatoms are selected from an oxygen atom, nitrogen atom, and sulfur atom, and/or which hydrocarbon group may contain a group selected from an amide bond or a urethane bond and which hydrocarbon group may further be substituted with up to 6 groups selected from \u2014COOZ\u2032, amino groups, hydroxyl groups and thiol groups; Y is a hydrogen atom, a \u2014COOZ\u2032 group, or a hydrocarbon group having 1 to 20 carbon atoms, wherein the hydrocarbon group may contain 1 to 6 heteroatoms, which heteroatoms are selected from an oxygen atom, nitrogen atom, and sulfur atom, and/or which hydrocarbon group may contain a group selected from an amide bond or a urethane bond and which hydrocarbon group may further be substituted with up to 6 groups selected from \u2014COOZ\u2032, amino groups, hydroxyl groups and thiol groups; Z\u2032 which may be the same or different, independently represents a hydrogen atom, a metal ion, a protecting group for a carboxylic acid group, or the Z\u2032 forms with a further \u2014COOZ\u2032 group present in the molecule an intramolecular anhydride group.
