Latest Patents
Richard P. Randall holds a patent for "Repulpable pressure-sensitive adhesive compositions." This invention describes a water-dispersible, inherently tacky pressure-sensitive adhesive. It comprises a tacky emulsion polymer formed from about 80% to 90% by weight of monomers, primarily alkyl acrylate containing 4 to about 8 carbon atoms in the alkyl group. The remaining 10% to 20% consists of a mixture of acrylic acid and at least one oleophilic unsaturated carboxylic acid. The emulsion polymer is created in the presence of anionic and nonionic surfactants, resulting in a polymer with a glass transition temperature ranging from -15°C to -50°C. This innovative adhesive allows for the recovery of paper fibers that are substantially free of adhesive when coated on a repulpable paper substrate, even under high humidity conditions.
