The invention discloses a monovinylarene-conjugated diene copolymer, a preparation method thereof and application of the monovinylarene-conjugated diene copolymer in preparation of tires. The monovinylarene-conjugated diene copolymer contains a monovinylarene structural unit shown as formula (I), a conjugated diene structural unit shown as formula (II) and a crosslinked structural unit shown as formula (III). R1-R6 can be identical or different, and are independently H or the alkyl of C1-C5's straight chain or branched chain; and R1'-R6' can be identical or different, and are independently H or the alkyl of C1-C5's straight chain or branched chain. The monovinylarene-conjugated diene copolymer has a low clod flow value. (formula I, formula II and formula III).
