摘要：A process for the separation of laminated components from polyurethaneadhesive bonded composite laminates is provided. In this process, the laminates aretreated with monofunctional aliphatic alcohols with 3 to 12 carbon atoms or mixturesthereof at temperatures of 100° C. to 200. degree. C. to alcoholize the polyurethane. Ifnecessary, water is added to the process. The alcoholysis product is removed and thecomponents are separated from each other. This process is particularly useful inseparating fabric components from expanded porous polytetrafluoroethylenemembrane.
