An increase in the hard segment content at constant prepolymer molecular
weight broadens the o relaxation and decreases its intensity. This is
accompanied by a shift of the peak temperature to a higher temperature. It
appears that the a ...

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 ...
