Novel chromium-containing compounds are prepared by forming a mixture of a chromium salt, a metal amide, and an ether. These novel chromium-containing, or chromium pyrrolide, compounds can be used as a cocatalyst in the presence of an olefin polymerization catalyst to produce a comonomer in-situ. The resultant polymer, although produced from predominately one monomer, has characteristics of a copolymer.
Nouveaux composés renfermant du chrome, préparés en formant un mélange de sel de chrome, un amide métallique et un éther. Ces nouveaux composés renfermant du chrome, soit des pyrrolide-chromes peuvent servir comme cocatalyseur en présence d'un catalyseur de polymérisation d'oléfines pour produire sur place un comonomère. Le polymère résultant, bien que produit principalement à partir d'un seul monomère, a les caractéristiques d'un copolymère.
