Patent

CA 2345621

(1) A catalyst for .alpha.-olefin production which comprises (a) a complex of a transition metal in Groups 8 to 10 of the Periodic Table, (b) a clay, clay mineral, or ion-exchanging lamellar compound, and (c) an amine compound or an adduct thereof with a Bronsted acid; (2) a catalyst for olefin polymerization which comprises (a) a chelate complex of a transition metal in Groups 4 to 6 of the Periodic Table or a complex of a transition metal in Groups 8 to 10 of the Periodic Table, (b) a clay, clay mineral, or ion-exchanging lamellar compound, and (c) a quaternary ammonium salt; and (3) a catalyst for vinyl compound polymerization which comprises: a promotor component obtained through contacting from (a) a clay, clay mineral, or ion-exchanging lamellar compound, (b) an amine compound, an adduct thereof with a Bronsted acid, or a quaternary ammonium salt, and (c) an organic silane compound; and (d) a complex of a transition metal in Groups 4 to 6 or Groups 8 to 10 of the Periodic Table.

L'invention porte sur: (1) un catalyseur de production d'.alpha.-oléfines comportant (a) un complexe d'un métal de transition des groupes 8 à 10 de la table périodique, (b) de l'argile, du minerai d'argile ou un composé lamellaire échangeur d'ions, et (c) un composé aminé ou l'un de ses adduits avec un acide de Bronsted; (2) un catalyseur de polymérisation d'oléfine comportant (a) un complexe chélaté d'un métal de transition des groupes 4 à 6 de la table périodique ou un complexe d'un métal de transition des groupes 8 à 10 de la table périodique, (b) de l'argile, du minerai d'argile ou un composé lamellaire échangeur d'ions, et (c) un sel d'ammonium quaternaire; et (3) un catalyseur de polymérisation de composés vinyliques comportant un promoteur obtenu par mise en contact de (a) de l'argile, du minerai d'argile ou un composé lamellaire échangeur d'ions (b) un composé aminé ou l'un de ses adduits avec un acide de Bronsted ou un sel d'ammonium quaternaire, (c) un composé organique de silane, et (d) un complexe d'un métal de transition des groupes 4 à 6 ou 8 à 10 de la table périodique.
