Heterogeneous polymer particles comprising an interpolymer domain of a monovinylidene aromatic monomer, an open chain aliphatic conjugated diene and a monoethylenically unsaturated acid

摘要

Aqueous latexes of heterogeneous polymer particles comprising (1) a soft interpolymer domain of a monovinylidene aromatic monomer, such as styrene, an open chain aliphatic conjugated diene, such as 1,3- butadiene, and monoethylenically unsaturated carboxylic acid, such as acrylic acid, and (2) a hard resinous polymer domain (e.g., polystyrene) are useful binders for pigmented paper coatings having an improved combination of properties.
