摘要

正

The morphology of some polyetherester-ureas were studied by

C CP/MAS and

H wide-line NMR spectroscopy. It was found that the HDI and MDI based polymers have well crystallized hard segments

whereas the TDI and HMDI based ones have not. For HDI/MDI based polymers

the presented results suggest that the distribution of two kinds of hard segment units is mainly in a block form. The influences of the different hard segment and chain length on the mobility of the soft segment were also studied.
