摘　　要：The thermal degradation of poly (ethylene terephthalate)(PET) and phosphorus containing copolyester,obtained from the polycondensation of terephthalate acid,ethylene glycol and 2 carboxyethyl (phenyl phosphinic) acid in air were studied by thermogravimetric analysis(TG) in order to determine the activation energy of phosphorus containing copolyester and PET.The activation energy was determined using Kissinger method and Flynn Wall Ozawa method,withaut the knowledge of the reaction mechanism(RM),giving the values 219.18～229.65kJ/mol and 217.61～238.85kJ/mol respectively.The results show that there is little difference between the values of thermogravimetric activation energy of phosphorus containing copolyester and PET,both of the reaction mechanism are same.The thermal degradation of poly (ethylene terephthalate)(PET) and phosphorus containing copolyester,obtained from the polycondensation of terephthalate acid,ethylene glycol and 2 carboxyethyl (phenyl phosphinic) acid in air were studied by thermogravimetric analysis(TG) in order to determine the activation energy of phosphorus containing copolyester and PET.The activation energy was determined using Kissinger method and Flynn Wall Ozawa method,withaut the knowledge of the reaction mechanism(RM),giving the values 219.18～229.65kJ/mol and 217.61～238.85kJ/mol respectively.The results show that there is little difference between the values of thermogravimetric activation energy of phosphorus containing copolyester and PET,both of the reaction mechanism are same.
