The invention discloses a high-performance polymer resin with a controllable melt viscosity, and a preparation method thereof, and belongs to the technical field of petrochemical industry. The methodcan realize the production of petroleum resin with an approaching softening point index and the controllable and adjustable melt viscosity by the adjustment of a technology, and concretely comprises the following steps: oil raw materials which include C5 diolefin, monoolefin, styrene and solvent oil are dropwise added into a reaction kettle, a Lewis acid catalyst is added, a reaction is carried out at a reaction temperature of 50-90 DEG C under a reaction pressure of below 1 Mpa for 0.5-4 h, and water washing and solvent removal are carried out after the reaction ends in order to obtain the final petroleum resin product. The obtained petroleum resin has a Gardner color of No.2 to No.5 color, a softening point of 70-104 DEG C and a melt viscosity at 200 DEG C of 40-300 cps. The petroleum resin with various differen
