In a low-odor polyethylene blend made from a high-molecular-weight ethylene
copolymer obtainable by polymerization in the presence of a Ziegler
catalyst and from a low-molecular-weight ethylene homopolymer or ethylene
copolymer obtainable by polymerization in the presence of a chromocene
catalyst on an oxidic support, the Al content of the high-molecular-weight
component is from 5 to 60 mg/kg, the Al content of the
low-molecular-weight component is from 0 to 5 mg/kg and the Al content of
the blend is from 1 to 55 mg/kg. Processes are described for preparing
blends of this type. Their use is described for producing moldings, in
particular hollow articles and pipes. Moldings, in particular hollow
articles and pipes, are produced from low-odor polyethylene blends.
