摘要

A permselective material comprising a polymer having an organosiloxane skeleton and containing a dispersed solid additive, wherein when oxygen and nitrogen are passed through a membrane comprising the permselective material, the relation between the permeability coefficients [cm 3 €¢ cm€¢ sec -1 €¢ cm -2 €¢ cmHg -1 ] of oxygen and nitrogen at a temperature of 23±2°C under a pressure difference of 1.05 atm to 1.20 atm through the membrane is expressed by Formula (1): 0.94 ‰¤ P O 2 P N 2 1 where P(O 2 ) denotes the permeability coefficient of oxygen, while P(N 2 ) denotes the permeability coefficient of nitrogen.
