    摘要： A method for producing a stable polymerized hemoglobin blood-substitute from blood. The method of this invention includes mixing blood with an anticoagulant to form a blood solution, washing the red blood cells in the blood solution and then separating the washed red blood cells from the white blood cells. This method also includes disrupting the red blood cells to release hemoglobin and form a hemoglobin solution, which is then treated by high performance liquid chromatography to form a hemoglobin eluate. The hemoglobin eluate is then deoxygenated, contacted with a first sulfhydryl compound to form an oxidation-stabilized deoxygenated hemoglobin solution, and mixed with a cross-linking agent to form a polymerization reaction mixture, which is then polymerized. The polymerized hemoglobin solution is then diafiltered with a physiologic solution and with a sulfhydryl compound, whereby the polymerized hemoglobin solution is made physiologically acceptable, and whereby the sulfhydryl compound scavenges oxygen, to form a stable polymerized hemoglobin blood-substitute.

    摘要： The present invention relates to a composition of matter comprising a stable polymerized hemoglobin solution, useful for forming blood-substitutes, and to a method for forming said stable polymerized hemoglobin solution. The stable polymerized hemoglobin solution, and derived blood-substitutes, of this invention comprise polymerized hemoglobin and a sulfhydryl compound, both in solution, wherein the sulfhydryl compound stabilizes the polymerized hemoglobin.The method of this invention comprises deoxygenating hemoglobin in a hemoglobin solution and then mixing the deoxygenated hemoglobin with a sulfhydryl compound to form an oxidation-stabilized, deoxygenated hemoglobin solution. Subsequently, the oxidation-stabilized deoxygenated hemoglobin solution is mixed with a cross-linking agent to form a polymerization reaction mixture, which is then polymerized to form a stable polymerized hemoglobin solution.

    摘要： A battery separator composed of a microporous sheet product having first and second major surfaces and a thickness of less than about 50 mils, formed from a uniform mixture of a polycarbonate polymer and a filler or a polycarbonate and a structure enhancing agent, said sheet product having a porous sheet embedded within said mixture and between the first and second major surfaces. The porosity of the sheet product is at least about 50 volume percent composed of pores such that the nominal pore diameter increases incrementally from each major surface towards the interior central portion of the sheet product's thickness.
