THERMOPLASTIC POLYURETHANES |
| 摘要 |
Thermoplastic polyurethanes exhibiting slowed annealing, reduced crystallinity, reduced viscosity sensitivity to shear, and improved hydrolytic stability are provided by utilizing small amounts of a polyether co-polyol with a polyester polyol and a symmetrical linear chain extender with small amounts of a different size chain extender. |
