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.

Abstract: A method of forming a monomer by reacting reactants including a first compound comprising an aromatic ring and a carbonyl group; a second compound comprising a carbonyl group; and optionally a third compound comprising an epoxide ring; wherein the monomer comprises a polyol (e.g., a polyphenol) or a polyepoxide. A polymer is provided that includes one or more segments derived from the monomer. The polymer may be used to prepare a coating composition, a coating, or a multi-part epoxide system. The coating composition may be applied to provide a coating on a food or beverage container.

Abstract: A method for making a monomer includes reacting an alkanol-substituted phenol with epihalohydrin in the presence of a phase transfer catalyst at a temperature of 50° C. or lower to produce a first intermediate product. The method further includes removing excess epihalohydrin, and after removing excess epihalohydrin, contacting the first intermediate product with a base to produce a second intermediate product, and forming an oxirane-functional vinyl monomer from the second intermediate product. The monomer includes an oxirane group, an unsaturated vinyl bond, and optionally an aromatic spacer between the two functional groups.

Abstract: An aqueous coating composition is provided that is preferably substantially free of bisphenol A. The coating composition is preferably a latex-based coating composition that includes a latex polymer formed from ingredients including an anionic and/or zwitterionic surfactant that includes one or more acid groups neutralized with a metallic base. The coating composition is useful in coating metal substrates such as, for example, interior and/or exterior surfaces of food or beverage containers.

Abstract: A coated food or beverage contact article that has been or will be ibrmed into a food or beverage container or container component, a method for making such containers or container components, coating compositions and polymers for use in such article or method. The coating composition comprises a polymer derived from or derived from or derivable from a polyphenol having two or more phenylene rings linked to or through an aliphatic or cycloaliphatic group or groups, wherein the polyphenol is a reaction product of a monophenol with a polyolefinic terpene. The polyphenol may be a diphenol and a reaction product of a monophenol with a diolefinic terpene. The terpene may be a cyclic terpene.
