| titleOfInvention |
Copolymers comprising a-olefins and olefin dicarboxylic acid esters, production thereof, and use thereof as pour point depressants for crude oils, mineral oils, or mineral oil products |
| abstract |
Copolymers comprising C14 to C50 olefins and at least two different olefindicarboxylic esters and optionally maleic acid or maleic acid derivatives. The olefindicarboxylic esters are firstly esters with linear C18- to C50-alkyl groups and secondly esters with short-chain linear, branched or cyclic alkyl groups, or esters with aromatic groups. The invention further relates to a process for preparing copolymers of this kind and to the use thereof as pour point depressant for crude oil, mineral oil and/or mineral oil products, preferably as pour point depressant for crude oil. |
