    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.

    摘要： Process for the polymerization of ethylene to produce a polymer of enhanced long chain branching. Ethylene and hydrogen are introduced into a first reaction zone to produce an ethylene polymer having a first molecular weight distribution. The polymer from the first reaction zone is applied to a second reaction zone along with ethylene and a C3-C8 alpha-olefin monomer. The second reaction zone is operated to produce a copolymer having a second molecular weight distribution different from the first molecular weight distribution. A polymer fluff of bimodal molecular weight distribution is recovered from the second reaction zone and heated to melt the fluff and then extruded. Concomitantly with the heating and or extrusion, the polymer fluff is treated in order to enhance the long chain branching and reduce the melt index MI5 of the polymer product.
