Association of Polyphosphazenes in Solution.

Abstract

Intrinsic viscosity data on poly(bis(trifluoroethoxy)phosphazene) (PBFP) in acetone exhibited negative slopes in Huggin's-Kraemer's plots. Solutions of PBFP at concentrations of 0.3, 0.4, 0.6 and 0.8 g/100 ml were examined in transmission with an FTIR spectrometer. The increase in absorptivity of the solutions was much less than proportional to the increase in polymer concentration, indicating that the calculated extinction coefficient decreased as the polymer concentration increased, implying polymer associated in solution.
