The kinetics of pyrolysis of two epoxide resins,hardened by maleic anhydride and by triethylenetetraamine,were studied by thermo—gravimetry.A comparison of various methods isothermal and non-isothermal thermo-gravime-try shows that the non-isothermal method gave sufficiently accurate kinetic data,as the isothermal method.The non-isothermal method is less time consuming and probably gives more representative values for the whole heating range.Kinetic data of isomerization of epoxy-groups have been obtained by differential thermal analysis.Useful informations about the chemical changes thking place in the heating process of epoxide resins can be obtained by ioint use of non-isothermal thermo-gravimetry,dif-ferential thermal analysis and thermo—mechanical methods.
