Abstract (en)
[origin: WO2017089212A1] The invention relates to copolymers comprising C14 to C50 olefins and at least two different olefin dicarboxylic acid esters and optionally maleic acid or maleic acid derivatives. The olefin dicarboxylic acid esters are, first, esters having linear C18 to C50 alkyl groups and, second, esters having short-chain linear, branched, or cyclic alkyl groups or esters having aromatic groups. The invention further relates to a method for producing such copolymers and to the use thereof as pour point depressants for crude oil, mineral oil, and/or mineral oil products, preferably as pour point depressants for crude oil.
