Abstract
Properties, surface composition, and blood compatibility of segmented poly(urethaneureas) (SPUU's) with
various soft segment components were investigated. The microphase separated structure between hard and
soft segments improved with an increase in molecular weight (Mn) of polyether diol in soft segment. The
amount of absorbed water depended on the nature of the polyether component. X-ray photoelectron spectra
of the surface of SPUU revealed that the surface composition depended on Mn and surface free energy of
polyether component. Blood compatibility of SPUU depended on the state of micro phase separated structure
and surface composition.
