Summary The influence of various nucleating agents on the crystallization parameters of polybutene-1 is reported. Isothermal crystallization is investigated by differential scanning calorimetry. The morphology induced by the differents nucleating agents has been observed by hot stage polarizing microscopy. It has been stated that the addition of nucleating agent affects the crystallization rate, dimension and homogeneity of spherulitic sizes. The induction time ti, the semicrystallization time t1/2, the crystallization rate constant K, and the Avrami coefficient n were measured and related to the different characteristics of the specimens. Because of the fractional values of n obtained in this study, it is not possible to propose well determined mechanisms of crystallization.
