<p>A process for producing a low polymer of an α-olefin which comprises lowly polymerizing the α-olefin in the presence of a catalyst and an organic solvent, wherein the low polymerization is conducted while cleaning the vapor-phase part wall of the reaction vessel by jetting a solvent comprising the organic solvent in the form of a linear or rod-like pressurized fluid toward the vapor-phase part wall of the reaction vessel from a nozzle disposed in the vapor phase in the reaction vessel. Thus, polymer deposition on the vapor-phase part wall of the reaction vessel can be effectively prevented and the reaction vessel can be stably operated over long.</p> |
