New segmented polyurethanes containing soft and hard segments of different polarity and hydrophilicity, based on 4,4^'-methylenebis-(cyclohexyl isocyanate, 4,4^'-methylenebis-(phenyl isocyanate) and poly(tetramethylene oxide) or poly(ethylene oxide) were prepared including poly[(N-acylimino) ethylene] sequences as a chain extender. They were comparatively characterized by spectral, thermal and mechanical techniques. Some preliminary investigations on their nanocomposites with montmorillonite as an inorganic component are presented.

Key Words: functional polymers • poly[(N-acylimino)ethylene] derivatives • polyurethanes • nanocomposites
