Abstract
A series of polyether-based thermoplastic polyure thanes, varying in hard segment content between 20 and 80 weight percent, was prepared using an (oxypropylene-oxyethy lene) diol of Mn = 2,000 and 4,4'-diphenyl methane diisocyanate (MDI) extended with 1,4-butanediol (BDO). Physical-mechanical, dynamic-mechanical and specific heat data are used to elucidate the behavior of these materials. The polyurethanes varied from soft elastomeric to high-modulus plastic.Keywords
