Differential scanning calorimetry study of cross‐nucleation between polymorphs in isotactic poly(1‐butene)
Cross‐nucleation is denoted as the heterogeneous nucleation of a ‘daughter’ polymorph on another pre‐existing (‘parent’) structure of the same substance. Several examples of the phenomenon for semicrystalline polymers have recently been reported. Polarized optical microscopy is commonly used to investigate both the morphology and the kinetics aspects of cross‐nucleation. Hereby, we propose a DSC approach for the quantitative investigation of cross‐nucleation in seeded crystallization. This case study deals with isotactic poly(1‐butene) Form II on Form I nucleation.
Seeds of the trigonal Form I were produced
