Abstract: The morphology of solution-cast thin films of isotactic poly(1-butene)(iPB-1) was investigated by using transmission electron microscopy(TEM) and electron diffraction techniques. The crystalline morphology of the solution-cast films of iPB-1 is greatly dependent on the preparation temperature. When the temperature is in the range of 90—100 ℃, metastable form Ⅱ spherulities are formed. Stable iPB-1 form Ⅰ crystals are achieved directly when the preparation temperature is higher(105—115 ℃).

Key words: Isotactic poly(1-butene), Crystallization behavior, Crystal structure
