Abstract

La présente invention concerne une dispersion aqueuse convenant à l'élaboration de compositions de peinture à l'eau contenant un matériau hydrophobe en dispersion, un support aqueux, un dispersant aqueux et un polymère ramifié (liant). Ce polymère ramifié, qui présente une masse moléculaire moyenne en poids d'environ 5.000-100.000 pour une teneur massique en ossature hydrophile de 20-80 % avec simultanément une teneur massique de 80-20 % en chaînes latérales de macromonomères. L'ossature est constituée de monomères éthyléniquement insaturés polymérisés pour 2-30 % de la masse des monomères éthyléniquement insaturés polymérisés portant un groupe à fonction acide. De plus, 10 % au moins des groupes à fonction acide, qui sont neutralisés par une amine ou une base inorganique, sont hydrophiles par rapport aux chaînes latérales. Enfin, les chaînes latérales sont des macromonomères de monomères éthyléniquement insaturés polymérisés formant par polymérisation l'ossature via un groupe éthyléniquement insaturé. Les macromonomères présentent une masse moléculaire moyenne en poids d'environ 1.000-30.000, le rapport pondéral hydrophile / liant se situant approximativement entre 1/100 et 200/100.
