Abstract :T he effect s of pho spho nate ester f lame re tardant (DP-FR)o n the rmal stability of f lame re tardant thermo plastic polyester elastomer (FR-TPEE)blends were studied .The kine tics o f the thermal o xidat ive degradation o f FR-TPEE blends w ere invest igated by non-iso thermal thermog ravime tric analy sis in air .Kissinger b and Fly nn-Wall-Ozawa b had been used to dete rmine the activat ion energies o f FRTPEE deg radatio n , respectively .The resul ts show ed that DP-FR had a li t tle inf luence on init ial deg radation temperature , maximum deg radation temperature and activ ation energies , but the FR-TPEE blends still had g ood thermal stabili ty .The result s also show ed that FR-TPEE blends had high char yield ,and also demo nst rated the good f lame retardancy of DP-FR .
Key words:thermo plastic po lyester elastomer (TPEE);f lame retardant (FR);kine tics ;thermal o xidat ive deg radation ;activation energy
