Title: The Innovative Contributions of Maddalena Pondrelli
Introduction
Maddalena Pondrelli is a distinguished inventor based in Budrio, Italy, known for her significant contributions to the field of polymer chemistry. With a total of nine patents to her name, she has made remarkable advancements in the development of catalysts for the polymerization of ethylene.
Latest Patents
Among her latest patents is a solid component of catalyst for the (co)polymerization of ethylene. This innovative catalyst comprises a silica carrier and a catalytically active part that includes titanium, magnesium, chlorine, and alkoxylic groups. The process for obtaining this catalyst involves suspending activated silica in a solution of magnesium chloride and titanium tetraalcoholate in a liquid aliphatic acid ester. Following this, the aliphatic acid ester is eliminated from the resulting suspension to recover a solid, which is then made to react with an aluminum alkyl chloride. Additionally, it is preferable to add measured quantities of a silicon halide to the solution in the aliphatic acid ester. Another notable patent is for a supported catalyst for the (co)polymerization of ethylene, which also features a silica support and a catalytically active part containing titanium, magnesium, chlorine, and alkoxy groups.
