Evaluation methods are described for the analysis of nonisothermal  kinetic processes exhibiting  topological nucleation  and growth characteristics. These evaluation methods are shown to be helpful  for studies being focused on kinetic data of polymer crystallization experiments with iPP (isotactic polypropylene) and PTFE (polytetrafluoroethylene) The take into account complications such as restricted  experimental  crystallinity ranges or fractal geometries of the growing crystallaties. The presented evaluation methods are based on the isokinetic nucleation and growth model of Nakamura and on the non-isothermal crystallization kinetics theory of Ozawa. Thus, the cooling functions χ(T) of iPP and PTFE, obtained by analyzing  differential scanning claorimetry experiments, are calculated for various cooling rates in two alternative ways by using clearly different mathematical approaches.
