PARTICULATE HYDROPHOBIC POLYMER, PRODUCTION PROCESS THEREFOR AND COLUMN FOR REVERSED-PHASE HIGH-PERFORMANCE LIQUID CHROMATOGRAPHY

摘要

A particulate hydrophobic polymer produced by reacting (A) a particulate crosslinked polymer having a hydroxyl group with (B) a crosslinkable epoxy compound, hydrolyzing the epoxy bonds, and then reacting the obtained compound having a hydroxyl group with (C) an epoxy compound having from 6 to 40 carbon atoms in total, a production process therefor, a column for reversed-phase liquid chromatography, and an analysis method using the column. By using the particulate hydrophobic polymer of the present invention having a remarkably high acid/alkali resistance, a sharp chromatogram for polycyclic aromatic compounds is obtainable with the swelling and shrinkage of the particulate polymer itself reduced and without reducind the column efficiency among various solvents even when the eluent in the column is variously exchanged.
