A novel flame-retardant and anti-dripping copolyester ( PBPET ) was synthesized by polycondensation of terephthalic acid ( TPA ) and ethylene glycol ( EG ) with bis (hydroxyethylether ) of bisphenol A (BHEEB) and [ (6-oxido-6H-dibenz[ c, e] [ 1,2] oxaphosphorin-6-yl) methyl] butanedioic acid (DDP). The chemical structure of the PBPET was characterized with 1H-NMR spectroscopy and inductively coupled plasma atomic emission spectroscopy ( ICP-AES ), and the thermal stability was investigated by thermogravimetric analysis (TGA). The flammability of the copolyesters was characterized by the limiting oxygen index (LOI) and UL-94 vertical test. TGA results suggested that BHEEB could effectively improve the thermal stability of the copolyesters, and the residues of PBPET at 600°C in N 2(Wt600R) reached 18.0 wt% . The flame-retardant tests proved that by incorporating both BHEEB and DDP into the polyesters, the resulting copolyesters exhibited expected flame retardance with an LOI value of 37.0 and a UL-94 V-O rating. Moreover, the anti-dripping behavior of the copolyesters was improved by the incorporation of BHEEB.
