Abstract
Polyethylene which comprises ethylene homopolymers and/or copolymers of ethylene with 1-alkenes and has a molar mass distribution width M/Mof from 3 to 30, a density of from 0.945 to 0.965 g/cm, a weight average molar mass Mof from 50 000 g/mol to 200 000 g/mol, a HLMI of from 10 to 300 g/10 min and has from 0.1 to 15 branches/1000 carbon atoms, wherein the 1 to 15% by weight of the polyethylene having the highest molar masses have a degree of branching of more than 1 branch of side chains larger than CH/1000 carbon atoms, a process for its preparation, catalysts suitable for its preparation and also injection moldings in which this polyethylene is present.
