Abstract

This invention provides a polymer, which is preferably a polyether polymer. The polymer may be uses in coating compositions. Containers and other articles comprising the polymer and methods of making such containers and other articles are also provided. The invention further provides compositions including the polymer (e.g., powder coatings), which have utility in a variety of coating end uses, including, for example, valve and pipe coatings.

Description

[0001] Cross References to Related Applications [0002] This application claims U.S. Provisional Application No. 61 / 440,085, filed February 7, 2011, entitled "COATING COMPOSITIONS FOR CONTAINERS AND OTHER ARTICLES AND METHODS OF COATING," and filed December 22, 2011, entitled "COATING COMPOSITIONS FOR CONTAINERS AND OTHER ARTICLES AND METHODS OF COATING", each of which is hereby incorporated by reference in its entirety. Background technique [0003] It is well known to apply coatings to metals to retard or inhibit corrosion. This is true in the field of packaging containers such as metal food and beverage cans. Coatings are often applied to the interior of such containers to prevent the contents thereof from coming into contact with the metal of the container. Contact between the metal and the packaged product may result in corrosion of the metal container, which may contaminate the packaged product. This is true when the contents of the container are chemically aggressi...
