Zusammenfassung:	The invention relates to a nylon toughening masterbatch and a preparation method thereof. The nylon toughening masterbatch is prepared by taking a polyolefin elastomer, nylon, a grafting monomer, an initiator, a diluent and a coating agent as raw materials through the steps of mixing the raw materials, adding the obtained mixture into an extruder, carrying out molten plasticizing, and sequentially extruding, granulating, cooling, dewatering and drying the obtained product. According to the invention, the grafting of the polyolefin elastomer and the manufacturing of the nylon toughening masterbatch are completed in one step, and the toughening masterbatch can be directly applied to the toughening of nylon injection products so as to increase the toughness of the nylon products. Because the nylon toughening masterbatch is manufactured by using a one-step method, energy sources can be saved, the processing cost is lowered, and the degradation of polymers is reduced.
