Abstract: A catalyst composition for the polymerization of propylene is provided. The catalyst composition includes one or more Ziegler-Natta procatalyst compositions having one or more transition metal compounds and one or more esters of aromatic dicarboxylic acid internal electron donors, one or more aluminum containing cocatalysts and a selectivity control agent (SCA). The SCA is a mixture of an activity limiting agent and a silane composition. The catalyst composition has a molar ratio of aluminum to total SCA from 0.5:1 to 4:1. This aluminum/SCA ratio improves polymerization productivity and the polymer production rate. The catalyst composition is self-extinguishing.

Abstract: Disclosed are methods for the production of polymers, including random copolymers (RCPs), in single reactor gas or slurry phase polymerization processes, and polymer compositions produced therefrom. The methods enable polymers having low melting temperatures to be made in gas and slurry phase polymerization processes, where they conventionally could not be made in these processes due to stickiness and fouling problems in the reactor.

Abstract: A mixed magnesium dialkoxide particulate obtained by direct solid-liquid reaction between particulate magnesium metal with a mean particle size of 50 µm to 500 µm and two or more alcohols including ethyl alcohol and at least one C3-6 alcohol, and comprising magnesium diethoxide, wherein the content of alkoxides other than ethoxide is 2.5 to 15 mol% of the total, the mean particle size (D 50 ) is 20 to 100 µm and the bulk density is at least 0.4 g/ml. The mixed magnesium dialkoxide is for use as a catalyst component for polymerization of olefins such as propylene, exhibits high breaking strength, and when used for preparation of a polymerization catalyst, high polymerization activity is exhibited resulting in a high catalyst product yield.

Abstract: A solid catalyst component for olefin polymerization makes it possible to polymerize an olefin with high polymerization activity when used for an olefin polymerization catalyst, and produce an olefin polymer having a low fine powder content, a low coarse powder content, and a low volatile organic compound (VOC) content in high yield. The solid catalyst component for olefin polymerization is produced by suspending (a) a dialkoxymagnesium, and (b) at least one alcohol selected from ethanol, n-propanol, n-butanol, isopropanol, isobutanol, and t-butanol, in an inert organic solvent so that the total amount of the alcohol is 0.5 to 1.5 parts by mass based on 100 parts by mass of the dialkoxymagnesium, to prepare a suspension, and bringing (c) an internal electron donor and (d) a titanium halide compound into contact with the suspension.

Abstract: Disclosed are spherical magnesium-based catalyst supports and methods of using the same in a Ziegler-Natta catalyst system for the polymerization of an olefin. The spherical magnesium-based catalyst supports are made by reacting a magnesium halide, a haloalkylepoxide, and a phosphate acid ester in an organic solvent that does not have to contain substantial amounts of toluene.
