Abstract
Fractionation of polydispersed polysiloxanes (1−2 g) into narrow molecular weight fractions has been achieved by a rapid (30−60 min) convenient process, using the Cyclograph Centrifugal Chromatography System. These narrow molecular weight poly(dimethylsiloxane) fractions can be used as secondary standards for GPC.Keywords
