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.
