P-1184 CROSSLINKED POLYETHERURETHANE MEMBRANES USEFUL IN BLOOD ELECTROLYTE SENSORS ABSTRACT OF THE DISCLOSURE Partition membranes which are permeable to blood electrolytes fabricated from crosslinked polyether- urethane compositions having from 20 to 50% hard segments. The membranes absorb from 50 to 120% of their dry weight of water and have electrolyte diffusion constants of up to 1 x 10-6cm2/sec. The membranes are included in electrochemical, fiber optic and solid state blood electrolyte sensors to provide blood compatible surfaces and to ensure that blood components deleterious to analysis of electrolyte in the blood remain separated from the sensing elements.
