ZIEGLER-NATTA PRODUCED POLYETHYLENE AND METHODS THEREOF

A process of producing a composition comprising a copolymer of ethylene and one or more C4-C8 α-olefins, may include copolymerizing the ethylene and the one or more C4-C8 α-olefins in the presence of a procatalyst and an alkylaluminum cocatalyst. The procatalyst may be a Ti-containing Ziegler Natta...

Abstract A process of producing a composition comprising a copolymer of ethylene and one or more C4-C8 α-olefins, may include copolymerizing the ethylene and the one or more C4-C8 α-olefins in the presence of a procatalyst and an alkylaluminum cocatalyst. The procatalyst may be a Ti-containing Ziegler Natta procatalyst and the polymerization may include the procatalyst and the alkylaluminum cocatalyst in amounts such that a molar ratio of Al:Ti ranges from about 0.5 to about 50.0. L'invention concerne un procédé de production d'une composition comprenant un copolymère d'éthylène et une ou plusieurs alpha-oléfines en C4-C8, peut comprendre la copolymérisation de l'éthylène et de la ou des alpha-oléfines en C4-C8 en présence d'un procatalyseur et d'un cocatalyseur d'alkylaluminium. Le procatalyseur peut être un procatalyseur Ziegler-Natta contenant du Ti et la polymérisation peut comprendre le procatalyseur et le cocatalyseur d'alkylaluminium en des quantités telles qu'un rapport molaire Al: Ti varie d'environ 0,5 à environ 50,0.
