    摘要: 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.
