    • This invention refers to a useful multipolymer in aqueous dispersion for application in the fields of coating, textile, adhesive, paper, civil construction, etc., and more specifically paints. Furthermore, the invention also refers to compositions containing a multipolymer and a process to obtain a multipolymer. The multipolymer in aqueous dispersion of the invention comprises at least four monomers, comprising a hard monomer, an ethylenically unsaturated carboxylic acid ester at the positions alpha , beta ; a monomer selected from a conjugated diene and butene and an ethylenically unsaturated carboxylic acid at the positions alpha , beta or amides of said acid. The economic architectural paints used for buildings when formulated with a multipolymer of the invention have higher washing resistance, less color fading than paints formulated with polymers currently used for the same application.
    • 本发明涉及用于涂料,纺织品,粘合剂,纸张,民用建筑等领域的有用的水性分散体聚合物,更具体地说是涂料。 此外,本发明还涉及包含多聚物的组合物和获得多聚物的方法。 本发明的水性分散体中的多聚物包含至少四种单体,其包含硬单体,α,β位置的烯属不饱和羧酸酯; 选自共轭二烯和丁烯的单体和所述酸的α,β或酰胺的烯属不饱和羧酸。 当用本发明的共聚物配制时用于建筑物的经济建筑涂料具有更高的耐洗涤性,比目前用于相同应用的聚合物配制的涂料更少的褪色。
