Latest Patents

Courtney S. Spain holds a patent for a unique procatalyst composition made with a combination of internal electron donors. This phthalate-free procatalyst composition is designed for olefin polymerization and exhibits excellent polymerization activity and response to hydrogen. The resulting polyolefin demonstrates high stereoregularity, high melt flow rate, and desirable molecular weight distribution. The method for producing this procatalyst involves the reaction of a magnesium support precursor with a tetravalent titanium halide and a combination of different internal electron donors. The first internal electron donor comprises one or more substituted phenylene aromatic diesters, while the second internal electron donor is a polyether, preferably a 1,3-diether. In one embodiment, the support precursor consists of a spherical spray crystallized MgCl-EtOH adduct.
