A process for polymerizing polyethylene with chromium-based catalysts wherein one or more supported chromium-based catalysts is mixed with mineral oil to form a slurry and the slurry is then introduced into a polymerization reactor, especially a gas-phase polymerization reactor.
L'invention concerne un procédé destiné à polymériser du polyéthylène avec des catalyseurs à base de chrome. Ce procédé consiste à mélanger un ou plusieurs catalyseurs à base de chrome supportés avec une huile minérale de manière à former une suspension, puis à introduire cette suspension dans un réacteur de polymérisation, et notamment dans un réacteur de polymérisation en phase gazeuse.
