Recent development in the techniques for the X-ray structural analysis of synthetic polymer crystals have been reviewed with some illustrations. In particular the usefulness of imaging plate system has been stressed and a new software for collecting quantitative data of the position and integrated intensity of the observed reflections has been introduced, which enabled us to apply the so-called direct method to the construction of the initial structural models necessary for the structural refinement. The structural changes of polymer crystals caused by an application of tensile force or by a temperature change have been discussed for two cases of polydiacetylene giant crystal and orthorhombic polyethylene.
