Abstract:
1. A crosslinkable vinyl ester copolymer obtained by free-radical-initiated polymerization of a) one or more vinyl esters and b) one or more ethylenically unsaturated, epoxy-functional monomers, and subsequent polymer-analogous reaction of the resultant parent polymer with one or more ethylenically unsaturated acids g), so that at least one ethylenically unsaturated, polymerizable group is introduced per parent polymer, wherein the molar mass Mn of the crosslinkable vinyl ester copolymer is ≧6500 g/mol; wherein the one or more vinyl esters a) constitute in a range from 20% to 99% by weight of all monomers used to prepare the parent polymer; wherein the polymer-analogous reaction is performed in the melt.
