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. Un método para formar un monómero al hacer reaccionar reactivos que incluyen un primer compuesto que comprende un anillo aromático y un grupo carbonilo; un segundo compuesto que comprende un grupo carbonilo; y opcionalmente un tercer compuesto que comprende un anillo de epóxido; en donde el monómero comprende un poliol (p. ej., un polifenol) o un poliepóxido. Se proporciona un polímero que incluye uno o más segmentos derivados del monómero. El polímero puede usarse para preparar una composición de recubrimiento, un recubrimiento, o un sistema epóxido de múltiples partes. La composición de recubrimiento puede aplicarse para proporcionar un recubrimiento en un recipiente para alimentos o bebidas.
