A block copolymer (A) including a vinyl alcohol-based polymer block (b) and an ionic polymer block (c) containing a monomer unit with an ionic group forming a salt and a vinyl alcohol-based monomer unit. The ionic group is a carboxylic acid group, a sulfonic acid group, or an ammonium group. The vinyl alcohol-based polymer block (b) has a number-average molecular weight (Mn.sub.b) from 15,000 to 220,000. The ionic polymer block (c) has a content of the vinyl alcohol-based monomer unit from 5 to 95 mol % based on the total monomer units. The block copolymer (A) has a number-average molecular weight (Mn.sub.A) from 20,000 to 440,000. A ratio (Mn.sub.b/Mn.sub.A) of the number-average molecular weight (Mn.sub.b) to the number-average molecular weight (Mn.sub.A) is from 0.1 to 0.9.

Functionalized particulate support material and chromatographic media prepared therefrom are disclosed. The functionalized particulate support material is a plurality of particles, each particle having a particle surface. Chemically bonded to and extending from the surface of the particles is a combination of hydrophobic and hydrophilic functional groups. The hydrophobic functional groups enable polymerization of one or more monomers onto the particle surface while the hydrophilic functional groups provide increased wettability of the particle surface compared to an unmodified particle surface. The functionalized particulate support material may be further processed so as to form polymer chains extending from the hydrophobic functional groups. In one embodiment, the resulting polymer functionalized material is useful as a chromatographic media in chromatography columns or cartridges, such as in a liquid chromatography (HPLC) column. Chromatography columns or cartridges containing the polymer functionalized media, and methods of making and using the media, are also disclosed.
