The invention discloses synthesis of a polyolefin rubber regenerant, and relates to the technical field of poly alpha-olefin copolymers. The polyolefin rubber regenerant is synthesized from the following raw materials: 30-45% of ethylene, 30-45% of propylene, 30-45% of 1-butene, 30-45% of an amorphous alpha-olefin copolymer formed by copolymerizing 6-8 carbon alpha olefin, 30-45% of propylene, 30-45% of 1-butene and 30-45% of 6-8 carbon alpha olefin. Propylene accounts for 35-45% of the total raw material dosage; 1-butene accounts for 25-30% of the total amount of the raw materials, 6-8 carbon alpha olefin accounts for 1-15% of the total amount of the raw materials, and the obtained alpha polyolefin copolymer is the rubber regenerant, when the alpha polyolefin copolymer is used for rubber regeneration, the alpha polyolefin copolymer has the advantages of being obvious in suitable tackifying effect, good in desulfurization effect, free of peculiar smell, capable of resisting oxidation, suitable for automatic l
