摘要： The present disclosure relates to novel procatalyst compositions including a titanium moiety, a magnesium halide support, a hydrocarbon solution in which the magnesium halide support is formed, and an electron donor modifier described herein. The present disclosure further relates to a one-pot process for preparing the novel procatalyst compositions, as well as use of the novel procatalyst compositions in solution processes for polymerization of ethylene and at least one addition polymerizable monomer to form a polymer composition.

摘要： A magnesium halide-supported titanium procatalyst, a catalyst prepared therefrom, an enhanced catalyst consists essentially of a product of a reaction of the magnesium halide-supported titanium procatalyst and a hydrocarbylaluminoxane. Also methods of preparing the (pro)catalysts, a method of polymerizing an olefin, and a polyolefin made by the polymerization method.

摘要： The present disclosure relates to novel procatalyst compositions including a titanium moiety, a magnesium halide support, a hydrocarbon solution in which the magnesium halide support is formed, and an electron donor modifier having the formula (I). The present disclosure further relates to a one-pot process for preparing the novel procatalyst compositions, as well as use of the novel procatalyst compositions in solution processes for polymerization of ethylene and at least one additional polymerizable monomer to form a polymer composition.
