As per the recommendations given by the ICTAC for kinetics, there have been thirteen kind of reaction model (P2, P3, P4, A2, A3, A4 and so on) is used to fit the right thermo decomposition model. Some polymer fits on single model and some about combination of two or three model, if any polymer does not fit with the recommended model by ICTAC, how do I determine the reaction model for that polymer?
Maybe you can find some information of thermal decomposition reaction model for a polymer in the following chapter.

Dear all,
if you have the experimental data you can develop your own model, using the best-fitting option of available softwares. It is not a fate to keep your results to most popular models. Regards
@Abdelkader BOUAZIZ,
Pls. Suggest me the softwares to develop my own model
basically, those models are based on chosing which is the best fitting one ...
regards
@Immanuel Richaud
Normally, the best fitting one is determined by R, If R is close to 1, that is 0.99, then it is chosen as best fit. But, some are having R value less than or nearer to 0.9, how can we take it as best fit one.
Hello dear Abdelkader, could you please tell me if these software are free? if it is true, could you please gift me a link. Thank you
Dear all,
well, the one we use efficiently is our simple experimental practices is ORIGIN, mainly the latest versions which are really rich with mathematical tools. Others also are used such as COMSOL. Regards
PS. I am not getting any alert from RG about the questions I am involved, the reason why I am responding too late, sorry for that.
Try to use a few determination method eg. Master plot, ikp, compwnsation effect, Perez
