Abstract
Disclosed herein is a polyhydroxy ketal adduct obtained by the esterification of a hydrocarbon polyol by at least 1.5 equivalents of a ketocarboxy to produce an intermediate ketocarboxylic ester. The intermediate polyketocarboxylic ester is then ketalized to produce the polyhydroxyketal adduct, which can be used to provide a polymeric composition.
