A coupled copolymer is provided. The coupled copolymer is coupled by reacting a silane coupling agent with a copolymer, where the copolymer is polymerized by a conjugated diene monomer and a vinyl aromatics monomer, and the silane coupling agent has an alkenyl group and a alkoxy group, and has a chemical Formula (I) as follows: where R1 and R4 are alkyl groups; R3 is a group having an alkenyl group; R5 is one of an alkyl and an alkenyl groups; q is one of "1" and "0"; when q=0, then k=j=0, 1@n@3, 0@m@2, m+n=3, and R2 is alkoxy group; and when q=1, then k+j=3, R2 is -(CH2)r, r=1-6 and m+n=3.
