Abstract

PURPOSE: To obtain the titled polymer having extremely uniform melt index and density, by detecting the concentration of a monomer and hydrogen, in a polymerizer inputting the values to a computer, adjusting polymerization conditions by calculating control output, carrying out polymerization using a Ziegler catalyst.
CONSTITUTION: In polymerizing an olefin using a Ziegler catalyst in the presence of hydrogen in the polymerizer provided with the hydrogen feed line 2, the olefin feed line 3, the catalyst feed line 4, the solvent feed line 5, and the pressure reducing line 6 having control valves a respectively, a hydrogen gas and olefin gas are introduced through the sampling line 8 equipped in the gaseous phase part 1b of the polymerizer 1 to the gas chromatography 9 and their concentrations are measured. Their signals are input to the computer 11, the control valves of all the lines are operated under previously programmed polymerization conditions by the output calculated based on the change in signal amounts so that polymeization is carried out always under constant conditions, to give the desired polymer from the outlet 7.
