Latest Patents
Juziu Yang holds 1 patent for his invention titled "Catalyst for the polymerization of propylene and its use." This patent describes a catalyst comprising components (A), (B), and (C). Component (A) is a solid product created by dissolving a halide of magnesium in a solvent system that includes an organic epoxy compound, an organic phosphorus compound, and an inert diluent. The process involves forming a homogeneous solution, mixing it with a halide of titanium, and precipitating a solid in the presence of an auxiliary precipitant. The solid is then treated with a polycarboxylic ester to load the ester onto the solid, followed by further treatment with the halide of titanium and the inert diluent. Component (B) consists of an organic aluminum compound, while component (C) is an organic silicon compound. The catalyst's particle size can be adjusted by varying the amount of the inert diluent at a low ratio of the epoxy compound to the phosphorus compound.
