BIO-DERIVED POLYURETHANE FIBER |
| 摘要 |
Included are elastomeric fibers and method for preparing such fibers, which include a bio-derived butanediol. The bio-derived butanediol is used to prepare a polymeric glycol composition, which is contacted with a diisocyanate and spun to provide an elastomeric fiber. |

1. A method for preparing an elastomeric fiber comprising:
(a) providing a polymeric glycol composition; from a bio-derived butanediol; (b) contacting said polymeric glycol composition with at least one diisocyanate; (c) dissolving the capped glycol in a solvent to provide a capped glycol solution; (d) contacting the capped glycol solution with a chain extender composition; and (e) spinning the solution to form the elastomeric fiber;
wherein said polymeric glycol composition includes at least one polymeric glycol which is prepared using from a bio-derived 1,4-butanediol. |
