With a total of 4 patents to her name, her work has had a substantial impact on the industry.

Latest Patents

One of her latest patents focuses on glossy paints containing emulsion polymers of vinyl acetate. These water-borne paints are formulated to achieve an ASTM 60° gloss value of at least 10. The formulation includes a latex of a copolymer of vinyl acetate and ethylene or alkyl acrylate, which has a dry glass transition temperature below 20° C. Additionally, it incorporates a latex of a polymer of vinyl acetate with a dry temperature above room temperature but a wet temperature below 23° C. This unique combination allows the paint to be film-forming at room temperature, making it suitable for satin, semi-gloss, or high gloss coatings, with a preference for semi-gloss paints. The addition of the higher temperature polymer enhances the paint's blocking resistance while maintaining low to no volatile organic content.

Another notable patent involves the use of vinylamine homopolymers and copolymers in film lamination. This patent describes a composite structure that includes a substrate layer, an intermediate adhesion layer, and a tightly adhered polymeric film. The adhesion layer is made from an aqueous emulsion polymer containing a vinylamine homopolymer or copolymer, specifically a polyvinyl alcohol/polyvinylamine copolymer.
