A method for synthesizing polyolefin materials with a controlled degree of branching includes the following steps: polymerizing cyclic olefin monomers under catalyst conditions. The cyclic olefin monomer is shown in formula I, where n≥0, n is an integer. By changing monomers and reaction parameters such as reaction temperature, solvent type, catalyst concentration, monomer concentration and reaction time, the degree of branching, the molecular weight and molecular weight distribution of polyolefin can be controlled. Compared with the existing process, the present invention is a new polymerization process, which can prepare the hyperbranched polyolefin with precise and controllable branching structure. The polyolefin material prepared according to the present invention has advantages of a controlled degree of branching, low viscosity and good fluidity, which has broad application in coating, lubricant, polymer and process flow improvement technologies.
