Synthesis and Characterization of Poly Phenoxyl Bisphenol-S Phosphate
Abstract:
A solid phase bisphenol-S bis(diphenyl phosphate)(BSDP), Poly Phenoxyl Bisphenol-S Phosphate(S-BSDP)was synthesized from phosphorus oxychloride, phenol and bisphenol-A in two step sythesis route. The influence factors on the yield and molecular weight of S-BSDP were investigated by the means of orthogonal design. The structure of S-BSDP was characterized with Fourier Transform Infrared Spectroscopy (FTIR). The molecular weight was determined by Gel Permeation Chromatography (GPC). Thermal stability of S-BSDP was studied by Thermal Gravimetric Analysis (TGA). The results review that S-BSDP was synthesized successfully and its structure is similar to BSDP. Its thermal decomposition temperature is much higher than liquid phase BSDP.
