The present invention discloses a poly-1-butene and a preparation method thereof. The method comprises that an olefin polymerization catalyst system and a 1-butene-containing monomer are continuously conveyed into a gas phase polymerization reactor under olefin polymerization conditions so as to be subjected to a gas phase continuous polymerization reaction, and the material obtained after the continuous polymerization reaction is discharged out of the gas phase polymerization reactor, wherein the olefin polymerization conditions comprise that the temperature is 60-85 DEG C and the pressure is 0.3-1.5 MPa, the residence time of the 1-butene-containing monomer in the gas phase polymerization reactor is 30-120 min, and the 1-butene-containing monomer contains 60-100 mol% of 1-butene. According to the present invention, the prepared poly-1-butene has high isotacticity (more than or equal to 97%) and low ash content, has a melting point of more than or equal to 110 DEG C, and is suitable for pipe preparation.
