Abstract: Polyacrylate esters having an average molecular weight of 1500 to 20,000 and being obtainable by the transesterification of alkyl polyacrylates, obtained by free radical polymerization and containing 1 to 4 carbon atoms in the alkyl group, witha) saturated or unsaturated aliphatic alcohols with 12 to 22 carbon atoms andb) optionally, additionally with dialkylaminoalkanols of the general formula HO--R.sup.1 --NR.sup.2 R.sup.3, wherein R.sup.1 is a divalent alkylene groups with 2 to 4 carbon atoms and are R.sup.2, R.sup.3 are the same or different and represent alkyl groups with 1 to 4 carbon atoms,the molar ratio of the aliphatic alcohols a) to the dialkylaminoalkanols b) being 1:0 to 1:1.5, and the components a) and b) being used in such amounts, that 25 to 70% of the ester groups are transesterified, are used as dispersants for finely divided solids, particularly for fillers and pigments, in organic media.
