ABSTRACT:
Latex of an interpolymer composed of (1) a copolymer A of butadiene, styrene and at least one ethylenically unsaturated carboxylic acid, and (2) a polymer B of at least one halogenoalkyl or halogenoacetoxyalkyl ester of an ethylenically unsaturated monocarboxylic or dicarboxylic acid, polymer B being at least partially grafted onto the copolymer A.
The latex is prepared by the emulsion polymerization of butadiene, styrene and at least one copolymerizable, ethylenically unsaturated carboxylic acid to form a copolymer latex, followed by the polymerization in the presence of the copolymer latex of a halogenoalkyl or halogenoacetoxyalkyl ester of an ethylenically unsaturated monocarboxylic or dicarboxylic acid.
The latex may be used as a binder in aqueous compositions for coating paper.
