<p>The present invention is directed to a dienophile-modified fatty acid composition and adhesive. The composition comprises
a) a polycondensate of
a1) a dimer of a fatty alcohol and/or a dimer of a fatty amine, and
a2) a dimer of a fatty acid,
said polycondensate having a weight average molecular weight of from 2,000 to 50,000 g/mol, and
b) a fatty acid derivative as a cross-linking agent, wherein said fatty acid derivative is obtainable by reacting
b1) a fatty acid ester comprising at least two double bonds, and
b2) a dienophile comprising at least one functional group selected from a carboxylic acid, a carboxylic acid ester and a carboxylic acid anhydride,
wherein the polycondensate and the cross-linking agent are capable of reacting with each other.</p> |
