Patent ID: 8008403

Claim:
A polyethylene which comprises a mixture of ethylene homopolymers and copolymers of ethylene with 1-alkenes, the polyethylene having an HLMI of 7 to 60 g/10 min, a molar mass distribution width M w /M n of from 7 to 15, a density of from 0.93 to 0.95 g/cm 3 , a weight average molar mass M w of from 50,000 g/mol to 500,000 g/mol and has 2 to 6 branches of side chains larger than CH 3 /1000 carbon atoms, a z-average molecular weight M z of less than 1 million g/mol, wherein 5-50% by weight of the polyethylene having the lowest molar masses has a degree of branching of less than 12 branches/1000 carbon atoms and 5-50% by weight of the polyethylene having the highest molar masses has a degree of branching of more than 1 branch/1000 carbon atoms.
