ABSTRACT:
Polyacrylate esters with long-chain hydrocarbon and polyoxyalkylene groups are disclosed, which are prepared by transesterification of polyacrylate alkyl esters, the alkyl groups of which have 1 to 4 carbon atoms and which were obtained by free radical polymerization, wherein the transesterification is carried out with a mixture of selected alcohols and polyoxyalkylene monools. Compared to products obtained by copolymerization, the transesterification products are largely free of undesirable low molecular weight components, have a narrow molecular weight distribution and exhibit excellent surfactant properties. They are useful especially as W/O emulsifiers for natural and synthetic oils.
