摘要: Abstract The practical applicability and the relevance of a classification processes into three different regimes is examined based on some typical TMDSC experiments. It demonstrated that this classification, simply presence temperature susceptibility an excess process, very useful to identify understand phenomena observed with TMDSC. ability separate base-line heat capacity from undoubtedly most valuable feature Nonetheless, one has realize restricted are not susceptible modulation such as for instance curing enthalpy recovery. Crystallization melting processes, other hand, thus complex in case uniquely determined by capacity. In addition, strong dependence kinetics combination generally large flow, imply conditions applied critical obtain reliable spite these serious limitations it can provide additional insight crystallization behaviour using (step-wise) quasi-isothermal measurements (i.e. β 0 =0).
