Polyacrylate polymer

A polymer comprising a polyacrylate homo- or copolymer backbone and at least one moiety derived from a compound of the general formula (I)

• wherein X, Y and Z are independently selected from the group consisting of hydrogen;
• halogen;
• substituted or unsubstituted, linear or branched C1-C10 alkyl;
• OR;
• and C(═O)—OR, wherein R is substituted or unsubstituted, linear or branched C1-C10 alkyl,
• wherein the at least one moiety derived from the compound of the general formula (I) is covalently bonded to at least one of the ends of the polyacrylate backbone;
• wherein the at least one moiety that is derived from a compound of the general formula (I) is present in an amount in the range from ≥3 wt. % to ≤10 wt. %, based on the overall weight of the polymer;
• and
• wherein the polyacrylate homo- or co-polymer backbone is obtained by polymerizing a mixture comprising at least one acrylate monomer of general formula (II),
• wherein R1 is selected from the group consisting of substituted or unsubstituted, linear or branched C1-C22 alkyl or C1-C22 cycloalkyl, substituted or unsubstituted aryl, substituted or unsubstituted aralkyl.
