Abstract: There is disclosed a polymer (Polymer P) which is obtained and/or is obtainable from a monomer composition comprising (a) from about 5% to about 95% by weight of at least one C2-12alkyl acrylate; (b) from about 2.5% to about 60% by weight of at least one polymer precursor selected from the group consisting of: C1-30 alkyl(meth)acrylates, C2-30 vinyl aromatic compounds, C2-30 vinyl halides, C2-30 vinyl nitriles, C2-30 vinyl esters of carboxylic acids and mixtures thereof; with the provisos that (i) the homopolymers of each of said polymer precursor(s) have a Tg above about −25° C.; and (ii) each of said polymer precursor(s) comprises other than a functional group selected from the group consisting of: hydroxy, carboxy, acid anhydride, nitro, epoxy and amino; (c) from about 0.1% to about 2% by weight of at least one polymer precursor comprising at least one activated unsaturated moiety (conveniently ethylenically unsaturated monomer) having at least one carboxy and/or acid anhydride group(s); and (d) optionally up to about 60% by weight of at least one further optionally substituted polymer precursor comprising at least one activated unsaturated moiety (conveniently ethylenically unsaturated monomer) where the further optional substituent(s) are other than carboxy and/or acid anhydride group(s) where each of the constituents ‘a’, ‘b’ and ‘c’ and optionally constituent ‘d’ are different from each other with the additional proviso that Polymer P was obtained and/or is obtainable by polymerisation of the each of the constituents ‘a’, ‘b’ and ‘c’ and optionally constituent ‘d’ in the presence of a water soluble initiator in an amount above about 0.35% and optionally up to about 2% by weight of the total monomer composition.
