Abstract

Theoretical gel permeation chromatography curves have been derived for model polydisperse polymers having chosen molecular weight averages and a given degree of random trifunctional branching. Gel permeation chromatography traces had been treated on a computer using the method proposed by Drott, and the molecular weight averages and a branching characteristic obtained were compared with those following directly from the model used (the Stockmayer type of distribution). The basic assumption of Drott (the ratio of the number of branch points to the molecular weight being constant) is discussed.
