PROCESS FOR CRYSTALLIZATION OF POLY(ETHYLENENAPHTHALENEDICARBOXYLATE) |
| 摘要 |
<p>A novel process has been developed for the crystallization of poly(ethylenenaphthalenedicarboxylate) (PEN) and its copolymers. The process comprises the step of maintaining the amount of water in said poly(ethylenenaphthalenedicarboxylate) below a critical moisture content ceiling throughout processing such that a separate drying step is not required.</p> |
