Versuchsvorschrift

A 1-liter continuous polymerization reactor was continuously charged hourly with 500 ml of purified toluene, 5×10-3 milligram-atom, as the zirconium atom, of the catalyst component (A) in Example 7 and 2.5 milligram-atom, as the aluminum atom, of the catalyst component (B) synthesized in Example 7. Furthermore, 150 liters/hr of ethylene, 100 liters/hr of propylene and 1.2 g/hr of 5-ethylidene-2-norbornene (ENB) were simultaneously fed into the reactor continuously, and polymerized at a temperature of 20° C. under atmospheric pressure with a residence time of 1 hour while the concentration of the polymer was maintained at 17 g/liter. The resulting polymer solution was worked up in the same way as in Example 7 to give an ethylene/propylene/ENB copolymer having an ethylene content of 83 mole %, an MFR of 3.59 g/10 min., an Mw/Mn of 2.10 and an iodine value of 13. The activity was 1,700 g of polymer/milligram-atom of zirconium.
