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 the title "METHODS OF PREPARING COMPOSITIONS FOR CONTAINERS AND OTHER ARTICLES AND METHODS OF USING SAME" ("METHODS OF PREPARING COMPOSITIONS FOR CONTAINERS AND OTHER ARTICLES AND METHODS OF USING SAME", filed April 14, 2014) method"), the disclosure of which is incorporated herein by reference in its entirety. Background technique [0003] The application of paints to metals to slow or inhibit corrosion is well established. This is especially true in the area of ​​packaging containers such as metal food and beverage cans. Paint is often applied to the interior of such containers to prevent the contents from contacting the metal of the container. Contact between metal and packaged product can lead to corrosion of the metal container, which can contaminate the packaged product. This is especially true when the contents of the container are chemically aggressive in nature. Protective coatings ar...
