Trends in adsorption of end-functionalized polystyrenes by thin-layer chromatography

摘要: The thin-layer chromatographic behavior on silica and alumina of polystyrene (PS-H), hydroxyl- terminated (PS-OH), carboxylic acid (PS-COOH) as a function molecular weight is reported. Functionalized samples below critical weight, which depends elution solvent, exhibit lower Rf values than PS-H the same weight. Above this value, similar observed. data describe regimes in solvent conditions under functionalized polymers adsorb through specific interaction between functional group surface.
