Copolymers comprising Cto Colefins and at least two different olefindicarboxylic esters and optionally maleic acid or maleic acid derivatives. The olefindicarboxylic esters are firstly esters with linear C- to C-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.

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

Copolymers comprising ethylene, vinyl esters, in particular vinyl acetate and esters of (meth)acrylic acid, selected from esters comprising branched alkyl, cyclic alkyl or optionally alkyl substituted aryl moieties and having a weight average molecular weight of 35,000 g/mol to 120,000 g/mol, formulations of such copolymers in organic solvents and their use as pour point depressant, wax inhibitor and flow enhancer for crude oils.

Copolymers comprising ethylene vinyl esters and esters of (meth)acrylic acid, their formulations and use as pour point depressant, wax inhibitor and flow enhancer for crude oils

Polymeric compositions obtainable by free-radical polymerization of at least two different alkyl (meth)acrylates in the presence of at least one ethylene-vinyl ester copolymer, the alkyl (meth)acrylates used being a mixture comprising alkyl (meth)acrylates having linear C- to C-alkyl radicals and different alkyl (meth)acrylates having linear C- to C-alkyl radicals and/or branched C- to C-alkyl radicals and/or cyclic C- to C-alkyl radicals. The use of such polymeric compositions as pour point depressants for crude oils, mineral oils or mineral oil products.

Polymeric compositions as pour point depressants for crude oils

Copolymers comprising ethylene, vinyl esters, in particular vinyl acetate and esters of (meth)acrylic acid, selected from esters comprising branched alkyl, cyclic alkyl or optionally alkyl substituted aryl moieties and having a weight average molecular weight of 35,000 g/mol to 150,000 g/mol, formulations of such copolymers in organic solvents and their use as pour point depressant, wax inhibitor and flow enhancer for crude oils.

Copolymers comprising ethylene, vinyl esters and esters of (meth)acrylic acid, their formulations and use as pour point depressant, wax inhibitor and flow enhancer for crude oils

The present invention relates to copolymers which are formed from specific amounts of (a) ethylene and (b) monomer(s) selected from propylheptylacrylate and propylheptyl-methacrylate, and optionally at least one further monomer. Said copolymers are useful as oil soluble additives for cosmetic formulations and especially oil depositioning enhancers for rinse-off formulations.
