ABSTRACT:
Stable, compatible, resin fortified aqueous vinyl polymer emulsions that are rich in wax are prepared in a method comprising a first polymerization of a mixture containing wax and monomers that include carboxylated monomers such as acrylic acid. The first polymerization or terpolymerization is carried out under conditions sufficient to produce a relatively low molecular weight resin. A portion of the wax rich resin from the first polymerization is neutralized and used as a cosurfactant in a second aqueous emulsion polymerization of vinyl monomers to produce a fortified vinyl latex that is rich in wax. Coatings prepared from the latex exhibit superior moisture barrier properties and are also useful as surface preservatives.
