摘要：
An ultrafiltration membrane comprised of a linear polyurethane having a hydraulic permeability for water of about 50 to 500 1/m.sup.2 .multidot. h and a separation factor .alpha. of about 2.times.10.sup.-3 to 1.times.10.sup.-4, the permeability being based on determination with a membrane of a thickness of about 0.02 mm, a pressure differential of 1 bar and a temperature of 20.degree. C. and the separation factor .alpha. being established with a 2% oil-water emulsion at 25.degree. C. The membrane is particularly suited for operation of oil-water mixtures or emulsions.
