High molecular weight thermoplastic polyurethanes made from polyols having high secondary hydroxyl content |
摘要 |
Thermoplastic polyurethane compositions are prepared from polyols having high secondary hydroxyl content, diisocyanates, chain extenders and catalysts. The resulting polyurethanes have high molecular weight and can be prepared by a one-shot process wherein the reactants and any additional desired components are brought together and reacted simultaneously or substantially simultaneously.
