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 ( M ̄_n) 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 M ̄_n and surface free energy of polyether component. Blood compatibility of SPUU depended on the state of microphase separated structure and surface composition.
