    摘要: 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.
