  • 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: 20230159783
    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: 20210230443
    Abstract: A food or beverage container having a body portion or an end portion that includes a metal substrate with a coating composition disposed thereon. The coating composition includes a water-dispersible acrylic linear block copolymer made by surfactant-free heterogeneous radical polymerization (“SFHRP”). The block copolymer imparts a desirable combination of flexibility and corrosion resistance to the coating composition, and the substantial absence of surfactants during polymerization contributes to other desirable properties including good blush resistance.

  • 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.

  • Patent number: 9944534
    Abstract: The invention provides a method of inhibiting the accumulation of DSP scale in the liquor circuit of Bayer process equipment. The method includes adding one or more particular silane based small molecules to the liquor fluid circuit. These scale inhibitors reduce DSP scale formation and thereby increase fluid throughput, increase the amount of time Bayer process equipment can be operational and reduce the need for expensive and dangerous acid washes of Bayer process equipment. As a result, the invention provides a significant reduction in the total cost of operating a Bayer process.
