Title:
オレフィンの(共)重合プロセスの触媒反応において使用するメタロセン錯体の活性化組成物
Document Type and Number:
Japanese Patent JP4808297
Kind Code:
B2
Abstract:
Organo-metallic composition without boron, comprising an extensively fluorinated organic compound, stable to the air, having a di-unsaturated cycle with five or six carbon atoms, and an alkyl derivative of magnesium or, preferably, of aluminum. Said composition can be used as activator of a metallocene complex of group 4 of the periodic table of elements to form a catalyst with a high activity and low metal content for the polymerization of alpha -olefins.
