PURPOSE:To prevent the deposition of polymer on the wall of a reactor, by polymerizing an olefin in the presence of an antistatic agent and a particulate solid catalyst component containing a transition metal compound in a polymerizer having the surface finished to a specified roughness or below. CONSTITUTION:A solid particulate catalyst component (the percentage of fine particles of a particle diameter <=2mu is below 10wt%) is prepared by contacting a transition metal compound (e.g. titanium tetrachloride) with a solid magnesium compound carrier. Then, a polyolefin is obtained by polymerizing an olefin (e.g., propylene) in a liquid phase in the presence of the above solid catalyst component and an antistatic agent (e.g., sodium di-2-ethylhexyl sulfosuccinate) in an amount of below 50mg per l of the liquid phase of the polymerization mixture in a polymerizer having the surface finished to a surface roughness of below 2.5mu, while maintaining the Reynolds number of the flow of the reaction mixture at above 5X10<4>.
