Reaktionsschritte

With the aid of 0.0015 part by weight of the titanium trichloride catalyst prepared as described in Example 3 (a) and 0.016 part by weight of isoprenylaluminum, 11 parts by weight of ethene is polymerized in 10 parts by weight of hexane with 5 parts by weight of a C4 -cut containing 45.6% trans-butene-2, 34.2% cis-butene-2, 18,1% butane and 2.1% butene-1 at a temperature of 85° C. first for 1/2 hour under a pressure of 6-7 atm. gauge. Thereafter, 0.001 part by weight of hydrogen is added and the polymerization continued under 7 atm. gauge. The ethene is added during the entire polymerization time of 3 hours. Subsequently, the polyethylene suspension is separated on a separating device and the polymer is dried, thus obtaining 10.5 parts by weight of a terpolymer of ethene, butene-1, and butene-2 having the following characteristics:
