Abstract

L'invention concerne une dispersion polymère comprenant : a. un constituant de type liant comprenant des particules polymères dispersées dans une phase aqueuse; et b. un agent antigel comprenant un polymère dendritique ou un polymère hyperramifié qui est choisi parmi une poly(amido)amine (PAMAM), le polyglycérol (PGL) ou une combinaison correspondante, la PAMAM et/ou le PGL présentant un poids moléculaire inférieur à 1000 Da. L'invention porte également sur un procédé d'abaissement du point de congélation d'une dispersion de polymère, le procédé consistant à : mélanger la dispersion de polymère avec un agent antigel choisi parmi la PAMAM dendritique ou hyperramifiée, le PGL ou une combinaison correspondante, ladite PAMAM et/ou le PGL présentant un poids moléculaire inférieur à 1000 Da, et sur l'utilisation de la PAMAM, de PGL ou d'une combinaison correspondante pour abaisser le point de congélation de la dispersion de polymère.
