Synthesis of sulfone-containing polyphosphates: low temperature solution polycndensation of bisphenol S analogues and aryl phosphorodichlorides

摘要

This paper describes the synthesis of new sulfone-containing polyphosphates from the reaction of various aryl phosphorodichlorides with bisphenol S (BPS) and its analogues in a chlorinated hydrocarbon solvent under low temperarure conditions. The polyphosphates obtained were characterized by IR, ~13C and ~31P NMR spectra, elemental analysis, inherent viscosity, TGA, DSC, X-ray diffraction, solubility, LOI, contact angle and molar mass measurement.
