Abstract
A bulk process for the formation of hydroxyl-containing polymeric compositions comprising the reaction in the presence of a Lewis acid catalyst of a hydroxyl group containing ethylenic polymer with a cyclic ester in the absence of a solvent is described. The compositions have enhanced film-forming characteristics including flexibility, resistance to corrosion, and the like.
