Gel permeation chromatography of stereoisomers: model compounds oef poly(vinyl chloride)

Abstract The possibility of separating stereoisomers of 2,4-dichloropentane and 2,4,6-trichloroheptane bymeans of gel permeation chromatographh on columns packed with S-Gel 832 was investigated using a recycling technique with minimal zone spreading. The results are discussed from th viewpoint of the assumed sizes of the molecules and with respect to a possible interaction of dissolved compounds with the eluent used. The results may not only help to elucidate some aspects of the separation process, but also to find suitable conditions for preparative fractionation of the above compounds employed as models of the PVC chain.
