It is intended to provide a polymer which is scarcely eluted, has a high biocompatibility and is useful in a filter for selectively eliminating leucocytes. It is also intended to provide a filter for selectively eliminating leucocytes, a filtration apparatus for selectively eliminating leucocytes and a system for selectively eliminating leucocytes, each having the above-described polymer. The above objects can be achieved by providing a polymer which comprises from 8% by mol to 45% by mol of a unit originating in a polymerizable monomer having a polyalkylene oxide chain, from 30% by mol to 90% by mol of a unit originating in a polymerizable monomer having a hydrophobic group, and from 2% by mol to 50% by mol of a unit originating in polymerizable monomer having a hydroxyl group.
本发明旨在提供一种几乎不被洗脱、具有高生物相容性并且适用于选择性消除白细胞的过滤器的聚合物。还旨在提供一种用于选择性消除白细胞的过滤器、一种用于选择性消除白细胞的过滤装置和一种用于选择性消除白细胞的系统,每种都具有上述聚合物。通过提供一种聚合物,其中包括8%摩尔到45%摩尔的起源于具有聚烯烃氧化物链的可聚合单体的单元,30%摩尔到90%摩尔的起源于具有疏水基团的可聚合单体的单元,以及2%摩尔到50%摩尔的起源于具有羟基的可聚合单体的单元,可以实现上述目标。
