SPANDEX FROM HIGH MOLECULAR WEIGHT POLY (TETRAMETHYLENE-CO-ETHYLENEETHER) GLYCOLS |
摘要 |
The invention provides polyurethaneurea compositions comprising poly(tetramethylene-co-ethyleneether) glycol having high number average molecular weight, from about 1900 to about 4000 Dalton. The invention further relates to the use of high number average molecular weight 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 number average molecular weight, from about 1900 to about 4000 Dalton, and their use in spandex. |
