Cyclo Dehydration Reaction of Polyhydrazides. I. Kinetic Parameters Obtained with Nonisothermal Thermogravimetry


The thermal conversion reaction of poly-(1,3-phenyl-1,4-phenyl)-hydrazide into poly-(1,3phenyl-1,4-phenyl)-1,3,4-oxadi~le has been studied using thermogravimetry (TG). For the evaluation of the energie of activation and other kinetic parameters of this cyclo dehydration reaction a method developed by Ozawa was used, where polymer samples are heated with… (More)
