Abstract
Polyesters containing tertiary ester linkages and pendant methylene unsaturation along the polymer chain are prepared from dialkyl 2,2-dimethyl-4-methyleneglutarate by transesterification with sterically structured polyols, preferably neopentyl glycol. The resultant sterically hindered polyesters are useful as hardeners and resin binders for high solids coatings.
