Abstract: A latex binder composition comprises occluded composite particles containing at least a vinyl ester homopolymer or a copolymer thereof polymerized from acrylate and/or ethylene monomers, and a polymer polymerized from conjugated diene and/or vinyl substituted aromatic monomers and desirably unsaturated carboxylic acid monomers. The occluded composite particles are produced in the absence of crosslinking agents by first polymerizing the vinyl esters and optional acrylate and/or ethylene monomers, and subsequently in situ polymerizing the conjugated diene and/or vinyl substituted aromatic, etc., monomers in the presence of the vinyl ester latex particles. The occluded composite-particle latex contains phase separated domains which are neither a core-shell nor an inverted core-shell particle and provide properties which are superior to physical blends of the two classes of polymers when utilized as binders in paper coating formulations.

Abstract: A water based coating composition provides a stain resistant layer which adheres well to a substrate and is resistant to chemical attack by common household cleaning solvents such as isopropyl alcohol. The coating composition has a very low volatile organic compound content, thus providing an environmentally desirable alternative to organic solvent based coatings. The low volatile organic compound content of the composition substantially or completely eliminates the problems and expenses associated with solvent recovery for meeting chemical emission standards, and the potential for human exposure to solvent vapor is substantially eliminated or significantly reduced. The coating composition is aqueous based and incorporates a crosslinkable acrylic polymer latex, an amino resin crosslinking agent and a crosslinking catalyst. The polymer, crosslinking agent and catalyst are dispersed and/or solubilized in an aqueous medium.

Abstract: Disclosed is a water-based adhesive with enhanced effectiveness for bonding metal and rubber substrates for uses such as vibration damping devices. The adhesive is formulated from a latex which includes at least one conjugated diene and a macromonomer containing at least two ethylene oxide repeat units.
