The invention relates to the field of polymers, and discloses a monovinylarene-conjugated diene polymer as well as a preparation method and application thereof. The monovinylarene-conjugated diene polymer contains 6-45 wt% of an oligomer and 55-94 wt% of a high polymer, the oligomer is of a star-shaped structure, the high polymer contains a linear high polymer and a coupling high polymer, the DIN abrasion of vulcanized rubber of the monovinylarene-conjugated diene polymer is below 105 mm < 3 >, and the DIN abrasion of the vulcanized rubber of the monovinylarene-conjugated diene polymer is below 10 mm < 3 >. In the polymer, the content of a structural unit from monovinylarene is 5-20wt%, the content of a structural unit from conjugated diene is 80-95wt%, and the linear polymer has a structure of which the tail end is sealed by a silicon-containing compound. The monovinylarene-conjugated diene polymer disclosed by the invention has excellent wear resistance and relatively low rolling resistance.
