Abstract: The invention provides a polyurethaneurea composition comprising at least one diisocyanate compound and a poly(tetramethylene-co-ethyleneether) glycol comprising constituent units derived by copolymerizing tetrahydrofuran and ethylene oxide, wherein the portion of the units derived from the ethylene oxide is present in the poly(tetramethylene-co-ethyleneether) glycol at less than about 15 mole percent. The invention further relates to the use of such low ethyleneether content Poly(tetramethylene-co-ethyleneether) glycols in spandex compositions. The invention also relates to new polyurethane compositions comprising poly(tetramethylene-co-ethyleneether) glycols with such low ethyleneether content, and their use in spandex.

Abstract: The invention provides a polyurethaneurea composition comprising poly(tetramethylene-co-ethyleneether) glycol having from about 37 to about 70 mole percent ethyleneether content and ethylene diamine as the extender. The invention further relates to the use of high ethyleneether content poly(tetramethylene-co- ethyleneether) glycol as the soft segment base material in spandex compositions. The invention also relates to new polyurethane compositions comprising poly(tetramethylene-co-ethyleneether) glycols with such high ethyleneether content, and their use in spandex.
