| 发明名称 | Process for the preparation of hyperbranched hollow fibers | ||
| 摘要 | The invention relates to a process for the preparation of a hollow filament (F) based on one or several molten or dissolved hyperbranched polymers (P) and potentially one or several further polymers (FP), characterized in that the molten or dissolved hyperbranched polymer (P) or the mixture of the hyperbranched polymer (P) with the further polymer (FP) is passed through one or several spinnerets (S), wherein the ratio between the spinneret die-length (L) and the die-channel (Delta-D) is between 0.1 and 9.5. The process can be applied for the preparation of hyperbranched polyethersulfone (HPES) hollow filaments. | ||
