Water-in-oil emulsions, compositions, and methods that include a vinyl polymer having a pKa of less than 4 that includes anionic group-containing side chains and alkyl-Y-containing side chains, wherein Y is O or NR, wherein R is hydrogen or methyl, and wherein the alkyl group of the alkyl-Y-containing side chain has at least 4 carbon atoms on average in a cyclic, branched-, or straight-chain configuration and optionally including one or more heteroatoms.
L'invention concerne des émulsions eau dans huile, des compositions et des procédés comprenant un polymère de vinyle présentant un pKa inférieur à 4, comprenant des chaînes latérales contenant un groupe anionique et des chaînes latérales contenant un alkyle Y. Y représente O ou NR, R représente hydrogène ou méthyle, et le groupe alkyle de la chaîne latérale contenant un alkyle Y comporte au moins 4 atomes de carbone en moyenne dans une configuration à chaîne cyclique, ramifiée, ou droite, et comporte éventuellement un ou plusieurs hétéroatomes.
