    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.

    Abstract: Copolymers of average number molecular weight from about 300 to 5,000 comprising recurrent units originating (A) from alpha olefins, (B) from .alpha.,.beta. unsaturated .alpha., .gamma. dicarboxylic compounds, (C) from unsaturated acid esters of 1,2-diols, optionally etherified or esterified, and (D) optionally from acrylic esters, the proportions of the recurrent units being 5-60% for (A), 10-70% for (B), 10-60% for (C) and 0-60% for (D), at least one of recurrent units (A), (B) and/or (C) comprising at least 12 carbon atoms, and at least 10% of the recurrent units of said copolymer being (B) recurrent units of N-substituted imide type. These copolymers form additives useful to lower the pour point of middle distillates, particularly of gas-oils. The use of said additives at a concentration from 0.001 to 2% by weight results in a substantial decrease of the pour point of the treated middle distillates.
