Coagulable polymer solution with aromatic high-performance polymers dissolved in the solution, method for obtaining same, and use thereof

摘要: The invention relates to a wet and dry-wet coagulable polymer solution, in particular spinnable which is based on ionic liquids comprises content of aromatic high-performance polymers dissolved the solution form polyamides, polyamide imides, polyimides and/or polybenzimidazole have been removed from textile fiber materials containing pollutants, waste fiber, using liquid. contains 0.5 30 wt.% more than 0.01 wt.%, 3 has null viscocity 1.5 30,000 Pa s particular. further method for producing such use thereof fibers by or spinning films coagulation. advantage products obtained this manner that toxic pollutants sharply reduced negligible level, less 20 ppm, 5 ppm.
