## Abstract The liquid chromatographic behavior of sulfonated ureaโformaldehyde resins in aqueous eluents was investigated and a suitable molecular weight calibration was established at a column system, consisting of ฮผโPORASIL 60 ร and ฮผโBONDAGEL (linear). It was demonstrated, that in deionized wat
