　Polyurethane elastomers were prepared with the condition of various curing temperatures and the various ratios of curing and crosslinking agents. Simultaneous small-angle X-ray scattering and wide-angle X-ray diffraction measurements revealed that the change of a microdomain structure of hard segment and crystallization behavior of soft segment during mechanical deformation.
