Patent ID: 7928051

Claim:
A polyethylene which comprises ethylene homopolymers, copolymers of ethylene with 1-alkenes or mixtures thereof, having a molar mass distribution width M w /M n of from 3 to 30, a density of from 0.945 to 0.965 g/cm 3 , a weight average molar mass M w of from 50,000 g/mol to 200,000 g/mol, an HLMI of from 50 to 200 g/10 min, at least 0.2 vinyl groups/1000 carbon atoms 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 3 /1000 carbon atoms, and the 5-50% by weight of the polyethylene having the lowest molar masses have a degree of branching of less than 10 branches/1000 carbon atoms.
