We investigated the crystallization dynamics of P3MB1 under isothermal condition by synchrotron radiation X-ray scattering and optical microscopy. At a crystallization temperature (Tc) of 297 °C, needle-like crystals consisting of stacked lamellae formed. As Tc increased, the number of lamellar branches decreased and morphological transition (spherulite → axialite → needle-like crystal) occurred. The suppression of lamellar branching was attributed to the low viscosity of the molten portion at Tc.
