FIELD: chemistry.
SUBSTANCE: track membrane for blood filtration is made in form of porous polymer 10-30 mcm thick film. 15-35% of pores have diameter 0.02-0.07 mcm, 50-60% of pores have diameter 0.07-0.1 mcm, 5-10% have diameter 0.1-0.13 mcm. Total density of pores constitutes 0.9·109÷1.1·1010 pore/cm2.
EFFECT: invention makes it possible to increase catching ability of track membrane with respect to low-density lipoproteins in human blood with preservation of albumin fraction.
