Abstract: The present invention belongs to the field of resource utilization of waste plastics, and particularly provides a method for preparing a vinyl terminated polymer by rapidly pyrolyzing polyolefin with a laser. The preparation method includes the following steps: first, adding a light absorber with a certain concentration into polyolefin as a raw material through a melt mixing process; then initiating high-temperature decomposition of polyolefin through laser irradiation under a protective effect of an inert gas; and condensing and collecting a decomposed product to obtain the vinyl terminated polymer.
