Abstract (en)

[origin: EP0359061A1] Aqueous emulsion copolymerizates of (meth)acrylates of long-chain alcohols in closed aqueous phase contain the following monomer components as disperse-phase copolymerizates with long storage life: at least 50 wt.%, preferably at least 60 wt.%, or (meth)acrylates of C16-30 alcohols; 0 to 25 wt.%, preferably 5 to 10 wt.%, of (meth)acrylates of alcohols with not more than 8 carbon atoms; and 0.5 to 40 wt.%, preferably approximately 1 to 25 wt.%, of olefinically unsaturated mono- and/or dicarboxylic acids or their anhydrides with a total of up to 10 carbon atoms. Also described is the use of these aqueous emulsion copolymerizates to reduce the pour point or flow point of hydrocarbon mixtures, in particular crude oil or crude oil fractions, in which the above-mentioned copolymerizates can be incorporated into hydrocarbon mixtures of the above-mentioned type in the form of a highly-concentrated but very mobile disperse phase of aqueous emulsion copolymerizates.
