    摘要: 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.

    摘要: The present invention provides a composition comprising an unsaturated polycondensate comprising a component with at least one carbon-carbon double bond and at least two carboxylic acid groups or the respective diester derivatives, preferably itaconic acid or an itaconic acid diester, in combination with a diol or a dimer of a fatty alcohol and a diacid monomer different from the first mentioned component; and a component chosen from a tackifying resin and/or a low-Tg polyester polyol, and/or a plasticizer; wherein the unsaturated polycondensate is capable of being cured via a radical mechanism. The invention is also directed at an environment-friendly adhesive comprising said composition, at a method for preparing the adhesive and at the use of the adhesive for laminating a sheet or a film.
