The domain structure of segmented polyether polyurethaneureas is investigated by means of positron annihilation technique
small angle X-ray scattering and differential scanning calcrimetry. The experimental results show that the decrease of domain volume and free volume results from the increase of hard segment contents
and that the increase of domain volume and free volume results from the increase of molecular weight of soft segments.
