Polyolefins made preferably only from ethylene using a selected ethylene oligomerization catalyst to form .alpha.-olefins and a polymerization catalyst which can copolymerize ethylene and .alpha.-olefins produces a novel polymer which advantageous rheological properties.

Los polyolefins hechos preferiblemente solamente del etileno usando un catalizador seleccionado del oligomerization del etileno para formar alpha.-alpha.-olefins y un catalizador de la polimerización que pueda copolymerize el etileno y los alpha.-alpha.-olefins producen un polímero de la novela que las características rheological ventajosas.
