    摘要： Disclosed is a process for making a Ziegler-Natta catalyst having controlled particle size and distribution. It comprises altering the precipitation of a catalyst component from a catalyst synthesis solution including a soluble magnesium containing catalyst precursor by controlling the concentration of either the soluble magnesium containing catalyst precursor, wherein the average particle size of the catalyst component is increased, and the particle size distribution increased, with a decreased concentration of the soluble magnesium containing catalyst precursor; or of the precipitating agent, wherein the average particle size of the catalyst component is increased, and the particle size distribution increased with an increased concentration of the precipitating agent. Use of the invention enables improved catalyst consistency regardless of production scale and customizing of catalyst morphology to desired polymer morphology. The novel catalyst components may be used to prepare polymers, and end-use articles therefrom, having desirable properties. It is emphasized that this abstract is provided to comply with the rules requiring an abstract which will allow a searcher or other reader to quickly ascertain the subject matter of the technical disclosure. It is submitted with the understanding that it will not be used to interpret or limit the scope or meaning of the claims.

    摘要： A process for the polymerization of ethylene to provide an ethylene polymer of reduced Yellowness Index. A feed stream, comprising an inert hydrocarbon diluent containing ethylene in a minor amount, is supplied to a polymerization reactor. A chromium-based polymerization catalyst and a triethylboron co-catalyst are incorporated into the feed stream within the reactor. The polymerization catalyst will normally be used in an amount within the range of 0.008-0.1 wt. % of the diluent in the feed stream and the triethylboron co-catalyst is incorporated in an amount within the range of 0.1-50 ppm of the diluent. The polymer fluff from the reactor is heated to a temperature sufficient to melt the fluff which is then extruded to produce a polymer product. The Yellowness Index after high temperature aging is at least 5% less than the corresponding Yellowness Index of a corresponding polymer product produced without the triethylboron co-catalyst.

    摘要： A process for making a polyolefin catalyst component, catalyst and polymer resin is disclosed. Controlling the viscosity of a catalyst synthesis solution with the addition of aluminum alkyl alters the precipitation of the catalyst component from a catalyst synthesis solution. The average particle size of the catalyst component increases with an increased concentration of aluminum alkyl in the synthesis solution. The catalyst component can be produced by a process comprising contacting a magnesium alkyl compound with an alcohol and an aluminum alkyl to form a magnesium dialkoxide. Catalyst components, catalysts, catalyst systems, polyolefin, products made therewith, and methods of forming each are disclosed. The reaction products can be washed with a hydrocarbon solvent to reduce titanium species [Ti] content to less than about 100 mmol/L.
