Abstract
Nine thermotropic liquid crystalline terpolyesters based on vaniUic acid(V)
p-hydroxybenzoic acid(H) and poly(ethylene terephthalate)(E) were investigated by thermogravimetry to ascertain their thermostability and the kinetic parameters for thermal degradation. Overall activation energy data of the degradation had been calculated over the range 5 ~ 70% weight loss. The temperatures and the activation energy of the degradation lie in the ranges of 384 ~ 394 ℃ at a heating rate of 1℃/min and 176 ~ 205 KJ/mol at the weight loss of 5%
respectively
which suggests that the terpolyesters have good thermostability.
