a dc during isothermal crystallization for all crystallization temperatures. The orange arrow represents the increasing influence of the ICD according to Fig. 2. The change from open to closed symbols indicates the completion of the primary crystallization. b Normalized lamellar thickness dc at the end of primary crystallization vs. the ratio of the timescales τlc/〈τc〉. Depending on the ratio τlc/〈τc〉 different regimes are visible. The dotted lines are guides to the eye. The closed symbols are the data from a, open symbols represent already published data of PEO (open circles) and PCL (open squares) for two molecular weights (cross and line) measured at different Tc21. For PCL a constant value of 1 s was taken for 〈τc〉, corresponding to the lower limit of a possible αc-relaxation time and an upper limit of τlc/〈τc〉 as indicated by the broken arrow. Source data of a are provided as a Source Data file.
