FIELD: chemistry.
SUBSTANCE: invention relates to a polymer system with selectivity of adsorption and, in particular, to polymer systems with multiple pores, including transport pores and negative ion charge on their surface. Biocompatible and/or hemocompatible polymer system with selectivity of adsorption-size, including at least one polymer with multiple pores, wherein said polymer contains transport pores with diameter of 250-2,000 Å and effective pores with diameter from 100 to 250 Å, volume of transport pores of said polymer ranges from 1.8 to 78 % of capacity of pore space of said polymer, and effective pore volume varies from 22 to 98.2 % capacity of pore space, where capacity of pores is sum of effective pores and transport pores and where space of pores greater than 300 Å is equal to 2.0 % or less of total pore space.
EFFECT: invention enables to obtain adsorbents for hemoperfusion procedures, having high selectivity of adsorption of proteins of small and average size, except large proteins.
