    Abstract: The invention is a product, comprising a substrate and a film that limits the transmission of water vapor comprising a polymer derived from one or more nonionic monomers polymerized in the presence of at least one nonionic surfactant and in the absence of ionic surfactants. The cloud temperature of the at least one nonionic surfactant is preferably less than the polymerization temperature. The nonionic surfactant is preferably an alkylene oxide adduct of an alkyl alcohol, alkylbenzene alcohol or dialkylbenzene alcohol, wherein the number of alkylene oxide groups is less than or equal to 14. The invention includes a dispersion formed by polymerizing nonionic monomers at a polymerization temperature in the presence of at least one nonionic surfactant with a cloud temperature less than the polymerization temperature; a water vapor barrier composition; a film formed from the dispersion; a method of making the dispersion; a method of making a film; and a method of reducing the ability of water vapor to be transmitted with respect to a substrate.

    Abstract: The invention is a method of treating, restoring or sealing a surface comprising applying an emulsion comprising a latex polymer, a cationic emulsifier, and optionall y a recycling agent to the surface to wet the surface and depositing a surface treatment layer o n the surface, wherein the depositing step occurs while the surface is wetted. The invention also includes a surface pretreatment composition comprising water, at least one acrylic latex polyme r, an aromatic recycling agent, and at least one cationic emulsifier. Furthermore, the invention includes the surface resulting from the application of the emulsion used in the invention and concentrated emulsions for use with the surface treatment composition.

    Abstract: A composition comprising a polymer, wherein the polymer comprises at least one of: i) a blend of a first polymer comprising a reaction product of acetoacetoxyethyl (meth)acrylate monomer and a second polymer comprising a reaction product of castor oil (meth)acrylate monomer, and ii) a third polymer comprising a reaction product of acetoacetoxyethyl (meth)acrylate monomer and castor oil (meth)acrylate monomer. These polymer compositions can be cured by at least one of auto-oxidation and actinic radiation. Optionally, at least a portion of the acetoacetoxyethyl (meth)acrylate moieties in the polymer can be converted to a corresponding enamine by reaction with at least one of ammonia and an amine.
