英文摘要	a novel solid flame retardant cyclic 9,9-bis(4-hydroxyphenyl)fluorine (phenylene phosphonate) (cpfp) oligomer was synthesized in high yields by the reaction of phenylphosphonic dichloride with 9,9-bis(4-hydroxyphenyl) fluorine under pseudo-high-dilution conditions via polycondensation. detailed structural characterizations of this oligomer were conducted by matrix-assisted laser desorption/ionization time-of-flight mass spectrometry (maldi-tof-ms), h-1 nmr, p-31 nmr and ftir. furthermore, the flame-retardant efficiency of this oligomer in polybutylene terephthalate (pbt) was studied using limiting oxygen index (loi) and ul-94 tests. after the addition of cpfp, the loi increased and the ul-94 v-0 rating was achieved. the occurrence of an interaction between cpfp and pbt was elucidated by thermogravimetric analysis (tga), ftir and pyrolysis/gc/ms. the results showed that the cpfp oligomer could change the degradation path of pbt and improves the char formation of the pbt/cpfp system. the residual morphologies of residues of the pbt/cpfp25% system were investigated by scanning electron microscopy (sem). sem investigations revealed that the residual chars contained polyphosphoric or phosphoric acid, which plays an important role in the process of carbonization.
