Paper Title:
Study on Microphase Separation of Polyether-Urethane Block Copolymers
  Abstract

A set of polyether-urethane block copolymers were prepared that poly (tetramethylene oxide) PTMO was regarded as soft segment, 4,4'-methylenebis(phenyl isocyanate)(MDI) and m-diphenylamine (MDM) was regarded as hard segment in this article. The microphase separation of polyether-urethane block copolymer was investigated by using infrared spectroscopy(FTIR), differential scanning calorimetry(DSC), small-angle X-ray scattering(SAXS),there obtained that there are two phases structure in polyether-urethane block copolymers and degree of phase separation decrease with increasing hard segment weight content.
