Abstract
Disclosed herein is a polyketal adduct obtained by forming an ester between a hydrocarbon polyol and a ketocarboxylic acid to produce an intermediate polyketocarboxylic ester. The intermediate polyketocarboxylic ester can be purified via crystallization to achieve purities of greater than 99.0% and then ketalized to produce the polyketal adduct, which can be used in polymer compositions. The polyketal adduct I is obtained at high purity and at high yield.
