Polyesters polyols prepared from glutaric acid, succinic acid and adipic acid, and polyurethanes prepared therefrom

摘要

Preparation of new polyols from mixtures of dicarboxylic acids comprising glutaric acid, succinic acid and adipic acid and polyhydric alcohols, such as mixtures of acids which are derived from treated residues resulting from the industrial production of adipic acid. Preparation of new polyurethanes from these polyols by reacting the latter with polyisocyanates. Obtaining products possessing advantageous properties and interesting market for treated residues resulting from the industrial production of adipic acid.
