ABSTRACT:
The present invention provides a repulpable moisture vapor barrier. The moisture vapor barrier comprises a resin latex and a hydrophobic component having a crystalline platelet structure. Suitable resin latexes include polystyrene, styrene-acrylonitrile, styrene-acrylonitrile-butadiene, styrene acrylates, styrene-butadiene, carboxylated styrene butadiene, polyvinyl chloride, polyvinyl acetate, waterborne polyurethanes, alkyl acrylates, polyvinylidene chloride, ethyl vinyl chloride, and copolymers and terpolymers thereof. Preferably the hydrophobic component is suspended in means for suspending the component such as fully hydrolyzed polyvinyl alcohol.
