Abstract

Emulsions concentrées d'agents polymères améliorant le point de congélation comprenant au moins un polymère du type des copolymères éthylène-ester vinylique d'acide carboxylique en C1-C24 (PI) et/ou du type des esters d'acide polyalkyl(méthyl)acrylique (P2) et un milieu de support liquide (T), qui ne dissout ni P1 ni P2, ainsi que, comme agent émulsionnant, un copolymère de greffage ou bloc- A-Y, où A = segment de copolymère correspondant à P1 ou d'un (méthyl)acrylate d'alcanols en C1-C40 et Y = segment d'un polymère de monomères vinyliques, le milieu de support T étant approprié pour dissoudre les segments Y.
