POWDERED HYDROPHOBIC POLYMER AND COLUMN FOR HIGH-PERFORMANCE REVERSED-PHASE LIQUID CHROMATOGRAPHY

摘要

FIELD: physicochemical analytical methods.;SUBSTANCE: invention relates to filling materials for reversed-phase liquid chromatography and provides powdered hydrophobic polymer prepared by reaction of powdered cross-linked (meth)acrylate polymer having hydroxyl group with cross-linking epoxy compound followed by hydrolysis of oxyrane cycles and reaction of thus obtained hydroxyl group-containing compound with epoxy compound containing 6 to 40 carbon atoms. Resulting filling material is characterized by high acid/alkali resistance and capability of retaining column efficiency when making use of different solvents.;EFFECT: enabled chromatogram with sharp picks for polycyclic aromatic compounds.;10 cl, 1 tbl, 4 ex
