    Abstract: This invention provides a coating composition for use on a food-contact surface of a container (e.g., a food or beverage can) that includes a polymer having one or more segments of Formula T: -O-Ar-Rn-C(O)-O-R1-O-C(O)-Rn-Ar-O-, wherein each Ar is independently a divalent aryl group (i.e., an arylene group) or heteroarylene group; R1 is a divalent organic group; each R is independently a divalent organic group; and n is 0 or 1. Containers comprising the polymer and methods of making such containers are also provided.

    Abstract: The present invention relates to a method of coating a food or beverage can, the method comprising: forming a composition comprising an emulsion polymerized latex polymer, comprising: forming a salt of an acid- or anhydride-functional polymer and an amine in a carrier comprising water to form an aqueous dispersion; combining an ethylenically unsaturated monomer component with the aqueous dispersion; and polymerizing the ethylenically unsaturated monomer component in the presence of the aqueous dispersion to form an emulsion polymerized latex polymer; and applying the composition comprising the emulsion polymerized latex polymer to a metal substrate prior to or after forming the metal substrate into a food or beverage can or portion thereof. The present invention also relates to a food or beverage can having a coating composition disposed thereon and to a composition for use as a coating of a food and beverage can.
