| titleOfInvention |
Spandex from poly(tetramethylene-co-ethyleneether)glycols blended with polymeric glycols |
| abstract |
A polyurethaneurea composition comprises a reaction product of at least one diisocyanate compound, a polymeric glycol, a poly(tetramethylene-co-ethyleneether) glycol comprising constituent units derived by copolymerizing tetrahydrofuran and ethylene oxide (EO) wherein the portion of the constituent units derived from ethylene oxide is present in the poly(tetramethylene-co-ethyleneether) glycol from greater than about 37 to about 70 mole percent, at least one diamine chain extender, and at least one chain terminator. The invention further relates to the use of blends of polymeric glycols and poly(tetramethylene-co-ethyleneether) glycols as the soft segment base in spandex compositions. The invention also relates to new polyurethane compositions comprising polymeric glycols and poly(tetramethylene-co-ethyleneether) glycols, and their use in spandex. |
