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.
