PROCESS FOR THE PREPARATION OF DICARBOXYLIC ACIDS OR DICARBOXYLIC ACID ESTERS BY METATHESIS

The present invention relates to a process for the preparation of dicarboxylic acids or dicarboxylic acid esters comprising the following process steps: A1 provision of at least the following reactants: a1 - a first aliphatic compound having 5 to 40 carbon atoms with in each case at least one functional group of the general formula (I) and (II), wherein R1 is a saturated or unsaturated aliphatic group having 2 to 20, preferably 4 to 16 and particularly preferably 6 to 12 carbon atoms and R2 is a hydrogen atom or an alkyl group having 1 to 10 carbon atoms, preferably having 1 to 5 carbon atoms and particularly preferably having 1, 2 or 3 carbon atoms formula (I) and (II) and a2 at least one further aliphatic compound which differs from the first aliphatic compound, chosen from the group consisting of a2a a compound of the general formula (III) in which n is chosen from 1, 2, 3, 4 and 5; a2b a compound of the general formula (IV) in which R3 is a hydrogen atom or an alkyl group having 1 to 10 carbon atoms, preferably having 1 to 5 carbon atoms and particularly preferably having 1, 2 or 3 carbon atoms and R4 and R5 independently of each other are a saturated alkylene group having 1 to 14 carbon atoms, preferably having 1 to 10 carbon atoms and very particularly preferably 1 to 5 carbon atoms; A2 provision of at least one organometallic catalyst based on ruthenium; A3 bringing into contact of the reactants and the catalyst to obtain a product mixture and the catalyst; A4 separating off of the catalyst; A5 optionally division of the product mixture into products Pi, i being a natural number, and the reactants which remain; the process being a metathesis reaction, and the dicarboxylic acid obtainable therefrom and the dicarboxylic acid ester obtainable therefrom, a process for the preparation of a polymer and the polymer obtainable by this process.
