In this work we have used synchrotron x-radiation diffraction to follow in real-time the isotropic-smoetic phase transition of a side-chain liquid crystalline polymer. The analysis of the x-ray data indicated that the transition occurs within a very narrow biphasic region. As the transition takes place, the size of the smectic regions, as indicated by the width of the diffraction peaks, changed only very slightly before impingement, suggesting a two-dimensional growth pattern. A thermal investigation of the polymer paralleling the x-ray experiments was undertaken and a kinetic analysis applied to the resulting data. Qualitative agreement with a disk-like growth of the smectic regions was found. We have shown that the overall kinetics of the isotropic-smectic transition of a side-chain polymer can be studied by x-ray diffraction permitting the evaluation of several structural parameters. © 1993 John Wiley & Sons, Inc.
