Abstract: The present disclosure provides a coating composition useful as a coating on food cans, and particularly as interior white or gold food can coatings. The coating composition includes a polyester polymer preferably having a number average molecular weight (Mn) of less than 10,000, a glass transition temperature (Tg) of more than 60° C., and a hydroxyl value greater than 10 mg KOH/g resin. The polyester preferably includes one or more cyclic groups selected from a monocyclic group having five ring members or less, a polycyclic group, or both, preferably in a backbone of the polyester polymer.

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.
