Composition comprising activated and functionalized prepolymer

A composition comprising:

• a pre-polymer having activated and functionalized groups on a polymeric backbone, wherein the composition has a zeta potential in the range of from 0 to 45 mV,
• wherein the polymeric backbone of the pre-polymer is of a formula (-A-B—)n, where A is derived from a substituted or unsubstituted polyol and B is derived from a substituted or unsubstituted polyacid, n is greater than 1, and
• wherein
• (a) the polyol is a triol and B is a diacid selected from glutaric acid, adipic acid, pimelic acid, sebacic acid and azelaic acid, or
• (b) the polyol is a diol and B is a triacid,
• wherein the activated functionalized group on the polymeric backbone of the pre-polymer is an acrylate group containing the structure —C(═O)—CRp=CRqRr, wherein Rp, Rq, Rr are independently from one another, selected from the group consisting of H, alkyl, aryl, substituted alkyl, substituted aryl, carboxylic acid, ester, amide, amine, urethane, ether, and carbonyl.
