The invention provides ternary copolymer rubber with both double ends of a macromolecular chain being functionally modified. In the invention, a functionalization initiator and an end terminating method are employed so that different functional groups are formed on two ends of the molecular chain and meanwhile the two ends of the molecular chain have excellent binding force with carbon black/white carbon black. On one end, an organic lithium initiator having a protecting group is employed to enable the molecular chain to contain a [-Si-(OR)3] group, which is beneficial to nano dispersion of a filler in a rubber substrate; and on the other end, a carboxylic group is included so that interaction with carbon black is promoted, thereby promoting dispersion of the carbon black in the rubber substrate. Meanwhile, the two ends of the macromolecular chain act on the carbon black/white carbon black to reduce the freedom degree of a chain section between a final crosslinked point and a chain terminal in the rubber network, so that the macromolecular chain effectively participates in elastic recovery of the whole crosslinked network, thereby reducing energy loss during periodic deformation and improving heat generation and rolling resistance. The double-end-functionalized ternary copolymer rubber has low rolling resistance and high anti-moisture sliding performance, so that the rubber is an excellent high-performance tyre rubber.
