The procedure and the complete apparatus for measuring molecular weights are described* and illustrated in sufficient detail to make possible constructing the equipment. By using a dozen of the static osmometers simultaneously, a complete molecular weight determination can be made in 1 to 4 days. Representative data for standard government specification GR-S polymers and for samples of German Buna S-3 subjected to various treatments illustrate the results obtained.Reproducibility of osmotic heights is of the order of 5%.
