Abstract

The invention relates to a metathesis crosslinkable binder composition comprising: i) at least one polymer compris­ ing non-aromatic C=C double bonds, the polymer comprising an average of at least 4 unsaturated fatty acid residues per polymer chain, wherein at least one of the fatty acid residues has from C18 to C26 carbon atoms; and ii) at least a transition metal based metathesis catalyst according to formula (I) wherein L1 is a neutral amine containing electron donor ligand; L2 is an optional neu­ tral electron donor ligand; X1, X2 are independently from each other an anionic ligand; a, bin (X1)aand (X2)b of formula (I) are in­ dependently from each other an integer from Oto 4; R is selected from the group consisting oflinear or branched alkyl, cycloalkyl, aralkyl, aryl or their substituted equivalents; Ra is selected from the group consisting of hydrogen, linear or branched alkyl, cy­ cloalkyl, aralkyl, aryl, or their substituted equivalents; M is a transition metal selected from the group consisting of Ruthenium (Ru), Manganese (Mn), Osmium (Os), Tungsten (W) and Molybdenum (Mo); wherein two or more of any of L1, L2, X1, X2, R and/or Ra are optionally covalently linked together to form one or more cyclic groups, and wherein two or more of any of L1, L2, X1, X2, Rand/or Ra are optionally attached to a support.
