This work presents studies about the synthesis and thermal characterization of a new polymer synthetized from the chloride phenylphosphonic molecule containing. The interfacial polycondensation method was utilized for the synthesis at low temperature. As monomer were used the phenylphosphonic dichloride (PPDC) and the 4,4'-dihydroxybenzophenone (DHBP). The synthesis reactions were conducted at room temperature with heterogeneous medium and constant stirring. The polymer was characterized by FTIR, NMR 31P and MALDI-TOF, which proved the formation of a compound polyphosphonate. DSC and TGA showed that the vitreous transition occurs at temperature of 66.0 °C and that the value of 220.0 °C is the degradation temperature of the polymer. After thermal degradation process the percentage of residual material is around 22.0 wt%. These results suggest the possibility of application of this material as a flame retardant in polymer materials.
