AbstractStructural studies of oligobutadienediol‐based polyurethanes with various degrees of crosslinking were carried out. From absolute small‐angle X‐ray scattering, the degree of segregation of components was determined. It was concluded that a complete microphase separation of the different components is realized in all samples irrespective of the degree of crosslinking, and these polymers are two‐phase systems. While stretching, the fibrillar structure is
