Abstract

L'invention concerne des dispersions polymères à base de (méth)acrylates à longues chaînes latérales, ainsi que leur procédé de préparation. L'invention concerne également une composition de pétrole brut contenant un pétrole brut et la dispersion de polymère selon l'invention. L'invention concerne en outre l'utilisation de ces dispersions polymères en tant qu'inhibiteurs de paraffine afin d'améliorer les propriétés d'écoulement de pétrole brut, ainsi que leur utilisation afin d'améliorer le transport et/ou le stockage d'un pétrole brut.
