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.

Abstract: The invention relates to a method for the preparation of a hyperbranched polyester mixture obtainable by reacting a hydroxyl group containing carboxylic acid (B) with at least one carboxylic acid group and at least two hydroxyl groups with a diol (C) having a molecular weight of more than 100 g/mol, optionally in the presence of at least one further reactant, wherein the at least one further reactant is a polyol (A) having at least three hydroxyl groups under a reaction condition allowing ester and ether formation; and reacting the mixture resulting from step (a) with a hydrophobic carboxylic acid (D) resulting in the hyperbranched polyester mixture. The invention further relates to said hyperbranched polyester mixture and the use as wax inhibitor, as pour point depressant, as lubricant or in lubricating oils.
