Polymerization of ethylene with specific iron or cobalt complexes, novel pyridinebis(imines) and novel complexes of pyridinebis(imines) with iron and cobalt

The ethylene obtainable by a a 2,6 - pyridylaldehyde bis (III) and 2,6 of the n-acyl a bis (a) a (or one of a contact to any one. The obtained polymer is useful as moulding resin. The invention claims a novel 2,6 to pyridylaldehyde bis (III) and 2,6 of the n-acyl a bis (III), and 2,6 to pyridylaldehyde bis (III) and 2,6 of the n-acyl a bis (III) and iron and a novel preparation.
