Abstract
A process for preparing solutions of hemoglobin hyperpolymers by fractionating hemoglobin hyperpolymers having a nonuniform molecular weight distribution according to molecular weight using a polyhydroxy compound to precipitate different fractions of hemoglobin hyperpolymers, wherein each fraction has a different but more uniform molecular weight distribution as compared to the starting hemoglobin hyperpolymers. Preferably, the polyhydroxy compound is a polyalcohol, especially polyethylene glycol.
