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.
Claims33
An aqueous butadiene polymer latex prepared by emulsion polymerization of at least 60 weight percent dichlorobutadiene in the presence of a stabilizer selected from styrene sulfonic acid, styrene sulfonate, poly(styrene sulfonic acid) or poly(styrene sulfonate), wherein the weight percent is based on the weight of total monomers used to prepare the butadiene polymer.
An aqueous adhesive composition comprising an aqueous butadiene polymer latex prepared by emulsion polymerization of at least one butadiene monomer in the presence of a stabilizer selected from styrene sulfonic acid, styrene sulfonate, poly(styrene sulfonic acid) or poly(styrene sulfonate).
An aqueous composition comprising the following ingredients:
- (a) an aqueous butadiene polymer latex prepared by emulsion polymerization of at least one butadiene monomer in the presence of a stabilizer selected from styrene sulfonic acid, styrene sulfonate, poly(styrene sulfonic acid) or poly(styrene sulfonate);
- and
- (b) a phenolic resin.
A method for making an aqueous butadiene polymer latex comprising emulsion polymerizing at least 60 weight percent dichlorobutadiene in the presence of a stabilizer selected from styrene sulfonic acid, styrene sulfonate, poly(styrene sulfonic acid) or poly(styrene sulfonate), wherein the weight percent is based on the weight of total monomers used to prepare the butadiene polymer.
A method according to claim 32 wherein the anionic surfactant is selected from an alkyl sulfonate or alkyl aryl sulfonate. 34. A method according to claim 33 wherein the anionic surfactant comprises a sulfonic acid or salt of an alkylated diphenyl oxide.
