- W2023463334 abstract "The new applications of polypropylene glycols as chemical intermediates, particularly in the polyurethane field, have shifted emphasis from purely physical properties, such as density, viscosity, and volatility, to chemical properties, such as hydroxyl content, unsaturation, and molecular weight: Because much interest is also being shown in the uniformity of chain length, i.e., the “molecular purity” of the polypropylene glycol, methods were investigated for measuring this property. A liquid chromatographic procedure has been developed which will yield molecular weight distributions for polypropylene glycols in the 2025 number-average molecular weight range. The results approximate, but do not match, the values obtained by theoretical calculations. Details of the method and a typical distribution curve are presented." @default.
