    摘要: A process for preparing hydrocarbon blown rigid polyurethane foam using a novel compatibilizing agent. The compatibilizing agent is an alkoxylate adduct of a triglyceride with a hydroxyl value of about 100 or less. The triglyceride adduct has an ethylene oxide content of at least 40% by weight thereof. These adducts may be used alone or in mixture with other compatibilizers. The compatibilizers increase the stability of rigid foam formulation emulsions containing greatly increased hydrocarbon blowing agent levels while showing little or no adverse affect to physical properties of foams prepared therewith.
