Determination of branching distribution by concurrent GPC and sedimentation velocity experiments

Abstract

Abstract A method of determining the distribution of branching in polydisperse polymer samples is proposed. This method uses data from concurrent gel permeation chromatography and sedimentation‐velocity experiments. Tedious fractionation, which must precede other methods of determining long‐chain branching, is eliminated. An example of use of the method on the data of a sample of styrene–divinylbenzene copolymer is given.
