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 2):
The polymerizable polymer according to  claim 1 , wherein the first copolymerizable monomer is represented by the general formula (1): wherein R 1  is a hydrogen atom, a \u2014COOZ group or a straight chain or branched C 1-6  alkyl group which may be substituted by a \u2014COOZ group; R 2  is a hydrogen atom, a \u2014COOZ group or a straight-chain or branched C 1-6  alkyl group which may be substituted by a \u2014COOZ group; A is a single bond or a straight-chain or branched C 1-6  alkylene group which group may contain 1 to 3 heteroatoms in between two carbon atoms of the alkylene carbon chain, which heteroatoms are selected from an oxygen atom, nitrogen atom, and sulfur atom, and/or which alkylene group may contain in between two carbon atoms of the alkylene carbon chain 1 to 3 groups selected from an amide bond or a urethane bond; Z 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 forms with a further \u2014COOZ group present in the molecule an intramolecular anhydride group.
