Patent ID: 8563674

Claim:
A polyethylene which comprises ethylene homopolymers and copolymers of ethylene with α-olefins and has a molar mass distribution width M w /M n of from 11 to 60, a density of from 0.89 to 0.97 g/cm 3 , a weight average molar mass M w of from 5000 g/mol to 700,000 g/mol and has from 0.01 to 20 branches/1000 carbon atoms and at least 0.5 vinyl groups/1000 carbon atoms, wherein a part of the polyethylene having a molar mass of less than 10,000 g/mol has a degree of branching of from 0 to 1.5 branches of side chains larger than CH 3 /1000 carbon atoms.
