Synthesis of polyphosphates by the polyaddition of bisphenol-S diglycidyl ether and aryl phosphorodichloridates

摘要: In this study, we synthesized polyphosphates with reactive pendant chloromethyl groups by an addition reaction of the diglycidyl ether bisphenol-S (bisphenol-S epoxy, BPSE) aryl phosphorodichloridates. The obtained were characterized IR, 1H NMR spectra, elemental analysis, TGA, DSC, X-ray diffraction, and molar mass measurement. polyaddition proceeded very smoothly in aromatic solvents catalyzed quaternary ammonium or phosphonium salts such as tetrabutylammonium bromide tetrabutylphosphonium to produce a polymer having high molecular weight. Polymer B, containing bromine atom phenyl ring side chain, has higher Tg value (Tg = 58°C) than polyphosphate derived from phenoxy dichlorophosphate (PDCP). A PDCP begins lose 10% its at 278°C, percentage remaining 700°C is 44% under nitrogen. diffraction patterns revealed that all subsequent are amorphous. © 1997 John Wiley & Sons, Inc.
