Abstract: A polyaryletherketone with a wide molecular weight distribution and a preparation method therefor. The polyaryletherketone has a Tg of at least 143° C., a Tm of at least 330° C., a crystallinity of at least 20%, a PDI of 2.5-2.9, and a gel content of as low as 0.2%. An extrusion blending or solution blending method is used to prepare the polyaryletherketone with the wide molecular weight distribution and without a high branching degree. When the viscosity of the polyaryletherketone is the same at low shear strength, the viscosity at high shear strength is smaller, such that the processing difficulty of a product can be significantly reduced, expanding the applicable range of the product. The gel content of the polyaryletherketone is remarkably reduced, resulting in a more streamlined process in the preparation of a molded product without significant fish-eye appearances on a film due to aggregation of the gel.
