Abstract
The separation of acrylonitrile-butadiene copolymer (NBR) was investigated by high-performance liquid chromatography (HPLC). The copolymer was most successfully separated on the basis of chemical composition by using crosslinked 2-chloroacrylonitrile gel as the stationary phase and with a gradient elution of chloroform/n-hexane. The separation was found to be carried out by an adsorption mechanism and essentially independent of the molecular weight of the sample. The observed chemical composition distributions (CCD) agreed with those calculated from the copolymerization theory.Keywords
