Process for the production of polymer filaments having high tensile strength and modulus. |
摘要 |
The invention relates to a process for the production of polymer filaments by spinning a solution of a polymer, having a weight-average molecular weight Mw higher than 4.10<5> kg/kmole with at least 80 % by weight of solvent at a temperature above the gel point of that solution, cooling the spun product to below the gel point and stretching the obtained filament to a filament having a tensile strength of more than 1,5 GPa at room temperature. The polymer has preferably a weight/number-average molecular weight ratio Mw/Mn lower than 5. During stretching the filament can be twisted around its axis.
