摘要： Polyester polyols are produced from at least one carboxylic acid hydride and diethylene glycol by a process in which the formation of 1,4-dioxane is suppressed. These polyester polyols are useful for producing polyurethane (PUR) and polyisocyanurate (PIR) foams and metal composite elements containing these PUR or PIR foams.
