Abstract

PURPOSE: To obtain the gas permeable membrane with excellent selective oxygen permeability, chemical resistance and mechanical strength by introducing a disiloxane structure into a main chain of polyurethane.
CONSTITUTION: The membrane comprising poly (urethane/disiloxane) having a repeating unit shown by a formulaIis obtained. This polymer membrane has coefficient of oxygen gas permeability of 2.8×10-10cc.cm/cm2.sec.cm Hg and said value is about 50 times compared to that of a similarity prepared polyurethane membrane. Said film is insoluble in almost all org. solvents and breaking strength and elongation thereof are respectively 740kg/cm2 and 4% at an elongation speed of 50mm/min and at 25°C.
