摘要： The present invention relates to the technical field of polypropylene materials, and provides a polypropylene microsphere and a preparation method therefor, a 3D printing raw material, and a use. The polypropylene microsphere comprises 0.2 wt%-10 wt% of a structural unit derived from ethylene and 90 wt%-99.8 wt% of a structural unit derived from propylene, wherein a melting heat absorption curve of the polypropylene microsphere is obtained by means of a differential scanning calorimeter (DSC), and a half-peak width (Wm) of the melting heat absorption curve of the polypropylene microsphere is 4-10 °C. According to the polypropylene microsphere of the present invention, the crystallization sequence distribution of the polypropylene microsphere is uniform, and when the polypropylene microsphere is used for 3D printing, 3D printing melting is uniform, a product is good in performance, and the polypropylene microsphere has an industrial application prospect.

摘要： The present disclosure relates to a method for preparing a polyolefin using a supported hybrid metallocene catalyst. According to the present disclosure, a polyolefin having a narrow molecular weight distribution can be prepared very effectively by introducing a cocatalyst in an optimum conent in the presence of a supported hybrid metallocene catalyst containing two or more metallocene compounds having a specific chemical structure. The polyolefin prepared according to the present disclosure exhibits excellent uniformity in chlorine distribution in polyolefin during chlorination, thereby significantly improving elongation of the chlorinated polyolefin, compatibility with PVC and impact reinforcing performance. Thus, it exhibits excellent chemical resistance, weather resistance, flame retardancy, processability and impact strength reinforcing effect, and can be suitably applied as an impact reinforcing agent for PVC pipes and window profiles.
