“…The various methods, and the uses to which they have been applied, are described in a comprehensive review of the literature on high-polymer fractionation, recently published by Cragg and Hammerschlag (4). Some rather extravagant claims for fractionation by extraction from a "coacérvate" have been made by Gavoret and Duclaux (10) on a fractionation of polyvinyl acetate. However, there seems to be a confusion, in the stating of their concentration units, between "grams" and "grundmols".…”

The object of the work was to ascertain the characteristic features which could provide a basis for distinguishing between the formation of the coacervate and that of a new liquid phase resulting from the limited miscibility of components. Various multicomponent systems containing the polymer were examined, and as a model we examined a system unable to form coacervates in which the polymer was replaced by a small‐molecule substance of a similar solubility. Measurements of the changes in the volumes of the liquid phases were carried out and the polymer content in the particular phases was determined. It was ascertained that the characteristic feature for the coacervate is a maximum on the curve which indicates the dependence of the volume of the phase richer in polymer on the quantity of the nonsolvent used. The polyethylene terephthalate coacervate was obtained and certain new systems containing polyamides were proved to be able to form coacervates.
