Abstract
AbstractNew 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.
