摘要: The present invention provides a polymer brush-type filler which contains polymer chains at a high density and with a broad molecular weight distribution. Specifically, the present invention provides fine particles for chromatography comprising graft polymer chains obtained by grafting polymer chains via polymerization initiating groups on the surface of solid particles, wherein the graft polymer chains include specific repeating units, have a specific number average molecular weight and a specific molecular weight distribution and also have a high density of 0.03 chains/nm2 or more and 0.70 chains/nm2 or less.
