The present invention is concerned with the use of polymeric additives for paraffin-containing fluids as pour point depressants and low temperature flow improvers, wherein the polymers comprise styrene and maleic acid dialkyl ester building blocks. La présente invention concerne l'utilisation d'additifs polymères pour des fluides contenant de la paraffine tels que des abaisseurs de point d'écoulement et des additifs d'amélioration de l'écoulement à basse température, les polymères comprenant des blocs de construction à base de styrène et d'ester dialkylique d'acide maléique.
