摘要：
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.
