Abstract

Water-resistant, protein-based adhesive dispersion compositions and methods for preparing them are provided. The adhesive dispersions are prepared by copolymerizing a denatured vegetable protein, such as soy flour, that has been functionalized with methylol groups with one or more reactive comonomers, and preparing an acidic dispersion of the adhesive. The adhesive dispersions exhibit superior water resistance, and can be used to bond wood substrates, such as panels or laminate, or in the preparation of composite materials.
