This is consistent with other observations that the soft segment blocks crystallize
only when their molecular weight is in excess of 1000, although higher hard/soft
segment mixing present in these systems may also prevent the crystallization of ...

For unannealed samples, the low temperature thermograms contain the
transitions associated with the soft segments and are presented in Figures 9 and
10. The thermograms in Figure 9 show the low temperature transitions for various
...

found that the difference is largest for the sample with the highest hard segment
content. These results indicate that the soft segments in the sample with highest
hard segment content crystallize faster and can be explained by two separate ...
