PROCESS FOR THE PREPARATION OF THERMOPLASTIC POLYURETHANES BASED ON 1,5-NAPHTHALENE-DIISOCYANATE |
| 摘要 |
Thermoplastic polyurethanes (TPU) based on NDI are prepared by reacting specific, storage-stable NDI-based NCO prepolymers with chain extenders and granulatin g the largely reacted and cooled reaction melt. The TPU granules can then be processed to form shaped articles.
