The invention discloses a nitrogen-containing organic auxiliary preparation method of high-grafting-rate soluble polyethylene-graft-maleic anhydride. Steps: S1. Fully mix polyethylene, MAH, initiator, nitrogen-containing organics, paraffin oil and Antioxidant 168 in a high-speed mixer and stand for a period of time; S2. Conduct melt grafting through a twin-screw extruder with optimized temperature zoning. The extruded material is water-cooled, pelletized and dried to obtain soluble PE-g-MAH with high grafting rate. As a compatibilizer, the product has high grafting efficiency and excellent processability. The regular macromolecular chain structure significantly enhances compatibilizing and toughening effects.
