Abstract

The present process is directed to preparation of addition polymers in diluents that are subsequently reactive in coatings during cure, instead of in traditional hydrocarbon solvents. The polymers so prepared can be used as the main film-forming polymer in high solids coating compositions, especially those useful for finishing automobiles and truck exteriors.
