This invention discloses a EPDM rubber and its preparation method, comprising copolymerizing the EPDM rubber from a first structural unit provided by ethylene, a second structural unit provided by propylene, and a third structural unit provided by a polyene monomer. This invention achieves precise control of the molecular structure of the EPDM rubber by introducing a polyene monomer with a specific structure as the third monomer, and combining it with a restricted geometry catalyst or a vanadium-based catalyst, thereby improving the uniformity of the copolymer and the vulcanization efficiency. The resulting rubber exhibits a narrow molecular weight distribution, suitable Mooney viscosity, and good processing properties, making it suitable for high-performance rubber products. The preparation method is simple, environmentally friendly, and easy to industrialize.
