    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 an emulsion-polymerized latex copolymer having copolymer chains of one or more mono-unsaturated monomers that are cross-linked with one or more multi-unsaturated monomers. The method also includes heating the sprayed coating composition to cure the coating composition, thereby providing the coating on the interior surface of the food or beverage container.

    Abstract: Metal food or beverage containers are coated with a polyether polymer containing at least two ether linkages in the polymer backbone. The polymer is substantially free of segments derived from bisphenol A and epoxides thereof, and is a reaction product of, or can be derived from, (i) an aryl- or heteroaryl-group-containing diepoxide that is not derived from a polyhydric phenol or a glycidyl ester and (ii) a polymer backbone extender that has two functional groups reactive with an epoxy group and which following reaction with the diepoxide provides at least one pendant aryl or heteroaryl group on the polymer backbone, or provides at least one divalent aryl or heteroaryl group in the polymer backbone and linked to the backbone via ether linkages.

    Abstract translation: 金属食品或饮料容器在聚合物骨架中涂覆含有至少两个醚键的聚醚聚合物。 该聚合物基本上不含源自双酚A及其环氧化物的链段，并且是（i）不衍生自多元酚的含芳基或杂芳基基团的二环氧化物的反应产物，或可衍生自 缩水甘油酯和（ii）具有两个与环氧基反应的官能团的聚合物主链延长剂，其与二环氧化物反应后与聚合物骨架上提供至少一个侧链芳基或杂芳基，或提供至少一个二价芳基或 杂芳基，并通过醚键与骨架连接。
