Synthesis and characterization of poly phenoxyl bisphenoI-A phosphate A new approach to get solid phase bisphenoI-A bis(diphenyl phosphate)

摘要

@@A solid phase Bisphenol-A Bis(Diphenyl Phosphate) (BDP)，Poly Phenoxyl Bisphenol-A Phosphate (S-BDP) was synthesized from phenyl dichlorophosphate and bisphenol-A by bulk polymerization. The influence factors on the yield and molecular weight of S-BDP were investigated by the means of orthogonal design. The structure of S-BDP was characterized with Fourier Transform Infrared Spectroscopy (FTIR). The molecular weight was determined by Gel Permeation Chromatography (GPC). Thermal stability of S-BDP was studied by Thermal Gravimetric Analysis (TGA). The results show that S-BDP was synthesized successfully and its structure is similar to BDP. Its Thermal decomposition temperature is much higher than commercial BDP flame retardant.
