ABSTRACT:
Waste or scrap polyurethane may be conveniently and economically converted to useful active-hydrogen containing polyethers and polyamines by contacting the polyurethane with water, strong base, and an activating agent such as a quaternary ammonium compound containing at least 15 carbon atoms or an organic sulfonate containing at least 7 carbon atoms. The activating agent helps to accelerate the rate of base catalyzed hydrolysis.
