摘要：
New hydrophobic-hydrophilic microphase-separated block segmented copoly(urethane-urea)s were synthesized by introducing hydrophobic polybutadienes as the soft segments and 4,4'-methylenediphenyl diisocyanate, hexamethylene diisocyanate, ethylenediamine, and a hydrophilic phosphatidylcholine analogue as the hard segments in the backbones of these polymers. The results of ATR-IR and XPS show the coexistence of phosphatidylcholine analogues and polybutadienes on the surface of cast films of the synthesized poly(urethane-urea)s. Furthermore, TEM cross sectional observation of the cast film PBDP-1370 indicates that it possesses a hydrophilic-hydrophobic microphase-separated domain structure.
