Abstract

Polyacrylate esters with long-chain alkoxylated hydrocarbonoxy groups are disclosed which can be obtained by the transesterification of polyacrylate esters with polyoxyalkylene monools, wherein the polyacrylate esters, up to 50% of which can be replaced by the corresponding methacrylate esters, have been obtained by free radical polymerization and wherein the polyoxyalkylene monools have the average formula EQU R.sup.1 O(C.sub.n H.sub.2n O--).sub.x H wherein PA1 R.sup.1 is an alkyl, alkenyl or alkylphenyl group, PA1 n has an absolute value of 2, 3 or 4 and an average value of 2.0 to 2.5 and PA1 x is 10 to 200. The compounds, which can be used as emulsifiers, solubilizers and for thickening aqueous solutions which contain anionic surfactants, particularly in cosmetics and for personal grooming, are distinguished by a content of low molecular weight components, which is smaller compared to that of products obtained by copolymerization.
