It is intended to provide a polymer for coating a leukocyte removal filter material which is excellent in the capability of removing leukocytes. It is further intended to provide a filter whereby both of leukocytes and platelets can be highly efficiently removed from a blood product containing leukocytes and platelets. The above objects can be achieved by using a polymer for coating a leukocyte removal filter material which comprises a unit originating in a hydrophobic polymerizable monomer, a unit originating in a polymerizable monomer containing a basic nitrogen-containing part, and a unit originating in a polymerizable monomer containing a protonic neutral hydrophilic part.
L'objectif de la présente invention est de procurer un matériau filtrant d'extraction de leucocytes permettant d'extraire des leucocytes avec une grande efficacité. L'objectif est également de fournir un matériau filtrant permettant d'extraire avec une grande efficacité des leucocytes et des plaquettes d'une préparation sanguine contenant des leucocytes et des plaquettes. A cet effet, on utilise un polymère pour revêtir un matériau filtrant d'extraction de leucocytes comprenant une unité provenant d'un monomère polymérisable hydrophobe, une unité provenant d'un monomère polymérisable contenant une partie de base contenant de l'azote, ainsi qu'une unité provenant d'un monomère polymérisable contenant une partie hydrophile neutre protonique.
