Vandopløselige copolymerer af vinylacetat og maleaminsyrer, anvendelse heraf som fluidiseringsmidler eller high range vandreduktionsmidler til vandige suspensioner

摘要

Novel water-soluble linear copolymers of vinylacetate with monomeric addition products of amines, amino acids, amino groups containing aromatic sulfonic acids, amino alcohols of maleic anhydride. The copolymers are useful as fluidizers in water containing solid matter suspensions.
