title = "Role of hard segment induced nanosized domain on concentrated solutions and bulk properties of ether based thermoplastic polyurethanes",
abstract = "A systematic study was conducted to investigate the effect of hard segment molecular weight on concentrated solution and bulk properties of thermoplastic ether based polyurethanes (TPUs). The molar feed was used to determine the molecular weight of the hard segment, and the weight fraction of the hard segment was then calculated as the ratio of the molecular weight of the hard segment to the number average molecular weight of the TPU determined by GPC. Similar to the study of dilution solution properties [1], it was found that rheological properties in concentration solutions, thermal properties and mechanical properties in the bulk were significantly affected at low weight fraction of the hard segment. Also, a limiting weight fraction of the hard segment was found at about 0.4 at above which the increase in weight fraction of the hard segment has a diminishing effect on the rheological properties in concentrated solution, thermal properties and dynamical mechanical properties in bulk.",
