ABSTRACT:
For preparing crystalline, thermoplastic, low-pressure terpolymers of ethene with 0.1-5 mol % butene-1 and 0.1-3 mol % butene-2 having a density of 0.94-0.96 g./cm.sup.3, a liquid phase monomer mixture consisting essentially of ethene, 0.05-10 mol % butene-1 and 20-98.9 mol % butene-2 is polymerized with a mixed polymerization catalyst comprising (a) TiCl.sub.3 . nAlCl.sub.3 wherein n is 0.2-0.6, and (b) isoprenylaluminum in a molar ratio Al : Ti of about 2-20 to form said terpolymer.
