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.
