With the aid of a catalyst of 0.014 part by weight of the TiCl3 . 0.33 AlCl3 described in Example 1 and 0.022 part by weight of diethylaluminum chloride, 20 parts by weight of propene (99%) is polymerized under a pressure of 14-9 atm. gauge and a temperature of 70° C. after adding 0.00015 part by weight of hydrogen in 60 parts by weight of a butene-2-rich C4 -cut containing 0.4% of butene-1. After a polymerization period of 6 hours, 1.0 part by weight of ethene is introduced under pressure, and the polymerization is containued for another 4 hours. After passing the reaction mixture through nozzles in the presence of 0.1 part by weight of steam, a propene-ethene-butene-1 terpolymer is obtaining having the properties as shown in the Table.
