Fibre Chemistry Aims and scope

Abstract

The temperature—viscosity curves were obtained for polyphosphoric acid with a phosphoric anhydride content of 72 to 90.75%. It was found that the composition of PPA remains constant for an industrially sufficient time. The molecular-weight distribution of PPA with a different phosphoric anhydride content was determined with the published data and a scheme of the mechanism of hydrolytic degradation of PPA was proposed.
