COPOLYMERS, CONTAINING α-OLEFINES AND OLEFINIC ETHERS DICA- CONNECTIC CONCEPTERS, APPLICAPERS, CONSTRUCTION PERSONAL CONDITIONS, APPLICATION PROCESSES, AND THEIR WAYS OF THEIR RECEIVING AND THEIR APPLICATION AS A DEFLUENT TEMPERATURE OF AN OILING FOR UNCLEANED OIL, APPLICATIONS
The present invention relates to copolymers containing C — C-olefins and at least two different dicarboxylic acid olefinic esters and, if necessary, maleic acid or its derivatives. First, the olefinic esters of dicarboxylic acid are esters with unbranched C 1 -C 6 alkyl groups, and, secondly, esters with short-chain, unbranched, branched or cyclic alkyl groups or esters with aromatic groups. In addition, the present invention also relates to a method for producing said copolymers and their use as pour point reducers for crude oil, petroleum oils and / or products derived from petroleum oils, preferably as pour point reducers for crude oil.
