  • Patent number: 11981822
    Abstract: A method of forming a coating on a food or beverage container, which includes spraying a coating composition onto an interior surface of the food or beverage container, where the coating composition includes a latex copolymer and a metal drier or crosslinking agent. The latex copolymer is a reaction product of monomers that include (a) one or more styrene-mimicking monomers containing one or more cyclic groups and one or more ethylenically-unsaturated groups, at least a portion of such styrene-mimicking monomers being polycyclic monomers containing ring unsaturation, and (b) one or more other ethylenically-unsaturated monomers. Preferably, the coating composition is substantially free of each of BPA, PVC, other halogenated monomers, and optionally styrene. The method may also include curing the sprayed coating composition, thereby providing the coating on the interior surface of the food or beverage container.

  • Publication number: 20230416417
    Abstract: Water-dispersible or water-dispersed polymers are made by reacting (i) an unsaturated monomer containing one or more cyclic carbonate groups, or (ii) an unsaturated or saturated oligomer or polymer containing a plurality of cyclic carbonate groups, with a tertiary amine in the presence of an acid, or with an acid in the presence of a tertiary amine, or in the presence of an acid and a tertiary amine, to provide a water-dispersible or water-dispersed monomer, oligomer or polymer. When step a) provides a monomer or oligomer, the monomer or oligomer is reacted with one or more monomers in the presence of an initiator to provide a water-dispersible or water-dispersed polymer. When step a) provides a polymer, the polymer is optionally used to support emulsion polymerization of one or more unsaturated monomers in the presence of an initiator to provide a water-dispersible or water-dispersed further polymer.

  • Publication number: 20210403633
    Abstract: A liquid epoxy resin composition is provided. In preferred embodiments, the liquid epoxy resin composition is free of bisphenol A, bisphenol F, and bisphenol S, including epoxides thereof, and is useful in preparing a polyether polymer having utility in coating compositions, including, e.g., coating compositions for use on food or beverage containers.

  • Patent number: 11059989
    Abstract: A method of forming a coating on a food or beverage container, which includes spraying a coating composition onto an interior surface of the food or beverage container, where the coating composition includes a latex copolymer and a metal drier or crosslinking agent. The latex copolymer is a reaction product of monomers that include (a) one or more styrene-offset monomers containing one or more cyclic groups and one or more ethylenically-unsaturated pendant groups, at least a portion of such styrene-offset monomers being polycyclic monomers containing ring unsaturation, and (b) one or more other ethylenically-unsaturated monomers. Preferably, the coating composition is substantially free of BPA, PVC, and styrene. The method may also include curing the sprayed coating composition, thereby providing the coating on the interior surface of the food or beverage container.
