Abstract
The direct comparison of similar polymers was achieved by a technique of differential GPC which, according to Runyon provided a simple yet sensitive technique that was relatively insensitive to operational variables. In this procedure the ‘standard’ polymer was dissolved in THF or an alternative suitable solvent, and the solution was used as the eluent in the GPC.
