Abstrakt: | The isothermal crystallization and phase II # I transformation of bulk polybutene-1 at various temperatures has been characterized by X-ray diffraction. The crystallization rate can be increased or decreased by the addition of various solids, with sodium salicylate and talc, e.g., increasing the rate by >100% and decreasing the rate by >300%, respectively. The nucleating agents have no effect on the transformation rate, which is, however, increased slightly in the presence of water and ethanol and significantly in the presence of liquids which are solvents at elevated temperatures or by the application of tension, compression or temperature cycling. The transformation rate of non-treated polymer is greatest near 25 °C, decreasing at higher and lower temperatures. | ||||||||||
