摘要:The invention relates to a method for preparing a polyethylene having a terminal ketone function or a copolymer of ethylene and a 1,3-diene and optionally a vinyl aromatic compound which contains more than 50 mol% of ethylene and has a terminal ketone function; said method comprises a polymerization reaction of the monomers in the presence of a borohydrido-neodymocene complex and an organo-magnesium compound, followed by a coupling reaction with a compound having a nitrile function, and then a hydrolysis reaction.
