| Abstract: | The phase separation of the coreshell type polyacrylatepolyurethane cast films has
been studied by mechanodynamic test, IR and DSC methods. The results indicated that the
existence of hydrogen bondings between acetone C=O in the core and NH in the shell improves
the phase separation of the soft and hard segments in the shell, and also improves the
compatibility of the core and shell, breaking the short range order of the hard segments. |
