ABSTRACT:
Half-ester adducts and improved polymer-polyols, both useful in the production of polyurethane foams and other synthetic materials are provided, as well as synthetic end products. The half-ester adducts are produced by reaction between polyols and polycarboxylic compounds including dibasic carboxylic acids and dibasic carboxylic anhydrides.
