To improve flame retardation of poly(ethylene terephthalate) (PET) against burning, resorcinol bis(diphenyl
phosphate) (RDP), phosphorous containing flame retardant, was incorporated into PET backbone by radical reaction pathway.
Radical endcapping of PET with RDP was confirmed by spectroscopic and thermal analysis. From 400 MHz 31P solid state
FT-NMR spectrum of PET with RDP (PET-RDP), phosphorus spectra peak in RDP was found at ca. -10 ppm. Furthermore, P-C
bond stretching vibration peaks were found ca. 530 cm-1 in FT-IR spectrums of PET-RDP. These results indicated that RDP can
be chemically bound at the ends of PET by radical addition method. Thermal characteristics of pure PET (pPET) and PET-RDP
were measured and evaluated by TGA thermal analysis. There was not significant changes in thermal characteristics of
PET-RDP compared to that of pPET. |
