Description
Summary:Experiments are described to show that cis-1,4-polybutadiene can be fractionated using the elution chromatography technique of Baker and Williams. Changes have been made to the equipment to give easier and more reliable operation. A method of selecting solvents and precipitants is described and it is shown that by proper selection of solvent and precipitant, the resolution of the higher molecular weight fractions may be improved. The influence on the fractionation of temperature, concentration of polymer in the eluant and column loading are investigated. It is concluded that column loading is the most important factor in explaining reversals of limiting viscosity number in the fractionation results.
