Abstract
A process is disclosed for preparing a composition comprising a polybutyl ketone and a hydroxyester of an epoxidized polybutene wherein the epoxide groups of said epoxidized polybutene are at least 70% trisubstituted. Acid compounds are reacted with epoxidized polybutenes to obtain compositions of increased reactivity as compared with polybutyl ketone compounds. These compositions are useful as chemical intermediates to modify such materials as polyesters and polyurethenes, for applications such as coatings, foams, and sealants.
