| titleOfInvention | Ziegler-Natta Procatalyst Robust Spray Drying and Polymerization Procedure Using It |
| abstract | A method for the production of a Ziegler-Natta procatalyst composition in the form of solid particles and comprising magnesium, halide and transition metal fractions, said particles having a mean size (D50) of between 10 and 70 μm, and comprising at least 5 percent of particles having a hollow internal volume, substantially or completely enclosed by a monolithic surface layer (coating), said layer having an average coating thickness / particle size ratio (thickness ratio), determined by means of scanning electron micrography (SEM) techniques for particles having a particle size greater than 30 μm, greater than 0.2, the method steps comprising: a) providing a liquid composition comprising i) a halide compound magnesium, ii) a solvent or diluent, iii) a transition metal compound, wherein the transition metal compound is a titanium halide or a haloalcoholate of ti tanium having 1 to 8 carbon atoms for each alcoholate group, iv) optionally an internal electron donor, and v) optionally further a filler; b) spray drying the composition to form a spray dried particle; and c) collecting the resulting solid particles, characterized in that the concentration of the magnesium halide compound is present in an amount that is at least 90 percent of the saturation concentration in the solvent or diluent. |
