Beschreibung
Zusammenfassung:	The invention relates to aqueous polymer dispersions comprising at least one polymer obtainable by the reaction of at least one monomer M1 of the general formula (I): H2C=CH-C(O)OR, wherein R is an unbranched alkyl chain comprising from 18 to 22 carbon atoms, and optionally at least one monomer M2. The invention relates moreover to a method for the preparing of such aqueous polymer dispersion and the use thereof as pour point depressant for crude oil, petroleum, and petroleum products. L'invention concerne des dispersions aqueuses de polymères comportant au moins un polymère pouvant être obtenu par réaction d'au moins un monomère M1 de formule générale H2C=CH-C(O)OR (I), dans laquelle R représente une chaîne alkyle non ramifiée comprenant 18 à 22 atomes de carbone et éventuellement au moins un monomère M2. L'invention concerne également un procédé pour la préparation d'une telle dispersion aqueuse de polymères et son utilisation comme améliorant du point d'écoulement pour le pétrole brut, le pétrole et les produits pétroliers
