Date Feb. 4, 1993.An artificial blood substitute comprising Lewis acid-Lewis base salt film microcapsule having a perfluorocarbons encapsulated therein. The Lewis base may be a polyoxyalkylene adduct of an amine, having the structure: in which, independently, R2 = CH2OR1 or CH2N(R1)2 and R4 = H, CH3 or alkyl, and said Lewis acid may be a polyoxyalkylene derivative of a polymeric acid having the structure in which c- and d- type repeat units are randomly distributed within the polymer, c=70 to 3150, c-type repeat units comprise from 50-90% of the total polymer.
