| titleOfInvention | Preparation process of novel polyarylether fibers containing phthalazinone structure |
| abstract | The invention provides a preparation process of novel polyarylether fibers containing a phthalazinone structure, and belongs to the technical field of high polymer materials. The raw materials are dried and then dissolved in 1,1 ', 2, 2' -tetrachloroethane and/or p-chlorophenol to form 30-50% spinning solution by mass percentage concentration, and the dissolving temperature is 130-160 ℃. Then, defoaming the spinning solution, inputting the defoamed spinning solution into a spinning cylinder, extruding the defoamed spinning solution through a spinneret plate under the condition that the temperature of a heating cylinder is 130-160 ℃, and removing the solvent through a hot channel to obtain polyarylether precursor containing a phthalazinone structure, wherein the mass fraction of the solvent in the precursor is reduced to be below 5%; the raw yarn is extruded by a spinneret plate and then directly enters a heat shaft, and the temperature of the heat shaft is 220-260 ℃. The novel polyarylether fibers containing the phthalazinone structure, which are prepared by the invention, have the characteristics of high heat resistance level, high mechanical strength, good dielectric property, radiation resistance, various processing modes and the like. |
