A cement composition comprising portland cement, mineral aggregate and an additive including a latex prepared by aqueous emulsion polymerization of a monomeric mixture comprising styrene and butadiene in the presence of a seed polymer prepared by aqueous emulsion polymerization of styrene and a salt of 2-acrylamido-2-methylpropanesulfonic acid.
A cement composition comprising portland cement, mineral aggregate and an additive including a latex prepared by the process of aqueous emulsion polymerization of styrene and a salt of 2-acrylamido-2-methylpropanesulfonic acid to form a seed polymer and then sequentially adding a mixture consisting essentially of monomers comprising styrene and butadiene under emulsion polymerization conditions.
