Patent number: 8148475Abstract: Thermoplastic polyether polyurethane polymers are disclosed which are mixed with a crosslinking agent to achieve long run times in a melt spinning process to make elastic fibers. The crosslinking agent is preferably a polyether or polyester polyol reacted with a diisocyanate. A melt spinning process is also disclosed using a polyether polyurethane with a crosslinking agent. Long melt spinning run times can be achieved without experiencing excessive pressure buildup in the spinneret and fiber breakage. The thermoplastic polyether polyurethane polymers are made by reacting: (1) a blend of two or more hydroxyl terminated intermediates wherein one intermediate is a polyether intermediate and has a higher number average molecular weight than the other said polyether intermediates, and wherein the weighted average number average molecular weight of said blend is greater than 1200 Daltons; (2) at least one polyisocyanate; and (3) at least one hydroxyl terminated chain extender.Type: GrantFiled: June 29, 2004Date of Patent: April 3, 2012Assignee: Lubrizol Advanced Materials, Inc.Inventors: Ravi R. Vedula, Yona Eckstein, Yinbing Xia, James E. Bryson, Jr., Christopher A. Sprague, Julius Farkas
