A cross-linkable polymer is formed from monomers including a) a hydroxyl-group containing monomer of general formula (I) in which R<26> is hydrogen or C1-4-alkyl group, A<1> is -O- or -NR<27>- where R<27> is hydrogen or a C1-4-alkyl group or a group B<9> R-(OH)n; B<9> is a bond, a straight or branched alkylene, an oxaalkylene or oligooxa alkylene group; R<13> is a n + 1 functional (optionally substituted) C1-24 alkylene group, n is an integer of one or more; and b) a reactive monomer of general formula (II) in which R<19> is hydrogen or a C1-4-alkyl group or A<2> is -O- or -NR<21>- where R<21> is hydrogen, or a C1-4-alkyl group, R<12> is C1-24 straight or branched alkylene, oxaalkylene or oligo oxaalkylene group in which each alkylene group has 1 to 6 carbon atoms, A<3> is a band or -O-, each R<16> independently selected from C1-6-alkyl groups. Preferably the polymer includes zwitterionic monomer and is useful for providing stable biocompatible coatings on substrates.
