Synthesis and Characterization of Polysulfonyldiphenylene Phenylphosphonate with High Melting Range

摘要

Polysulfonyldiphenylene phenylphosphonate (PSPPP) with high melting range of 197 to 205°C was synthesized via molten polycondensation method. The effect of material ratio, reaction temperature and reaction time of the method was studied, and the preferred reaction conditions were obtained. The target product was characterized by FTIR and thermogravimetric analysis (TGA) was carried out to confirm the thermal stability. The PSPPP synthesized in this paper showed fairly good thermal stability.
