Abstract of the Disclosure The present invention is directed to improvements in non-toxic polyurethane compositions and separatory devices employing the same, such as hollow fiber separatory devices intended to be used in biomedical applications. The separatory device employs at least one separatory membrane suitable for the intended end use application which is secured, potted or sealed in a housing using a cured flexible polyurethane composition. The improvement in the polyurethane composition employed in the separatory device is achieved by reacting at least one NCO-terminated prepolymer and at least one polyol in the presence of a ricinoleic acid reactive catalyst. The catalyst reduces the curing time of the polyurethane resin and because it is sufficiently reactive with the NCO-terminated prepolymer, it is incorporated into the structure of the polyurethane and cannot be released during operation of the separatory device.
