Abstract
An aqueous composition that includes (A) a butadiene polymer latex that is prepared by an emulsion polymerization in the presence of a styrene sulfonate stabilizer and (B) a phenolic resin. A preferred aqueous butadiene polymer latex is one that is prepared by emulsion polymerization of at least 60 weight percent dichlorobutadiene monomer (based on the amount of total monomers used to form the butadiene polymer), in the presence of a styrene sulfonate stabilizer.
Claims9
An aqueous butadiene polymer latex prepared by emulsion polymerization of a monomer mixture comprising at least 60 weight percent, 2,3-dichloro-1,3-butadiene and from 0.1 to 30 wt. % of α-haloacrylonitrile in the presence of a stabilizer selected from styrene sulfonic acid, styrene sulfonate, poly(styrene) sulfonic acid or poly(styrene sulfonate) and an other anionic surfactant, wherein the weight percent is based on the weight of total monomers used to prepare the butadiene polymer.
