Abstract

The precipitation and redissolution separation of synthetic poly(styrene-co-divinylbenzene) were studied under optimized conditions that allowed the use of much lower flow rates, reduced solvent use while affording good separations within a short period of time. The molded copolymer monolithic columns used in a gradient elution high performance liquid chromatography mode constitute a viable, less expensive, and much faster alternative to size-exclusion chromatography (SEC) columns for the determination of the molecular weight parameters of polymers. The short molded monolith may be used for the separation of many other polymers utilizing suitable pairs of solvents and non-solvents.
