Title: **Innovative Contributions of Mamdouh A Al-harthi in Polymer Chemistry**

Introduction

Mamdouh A Al-harthi is a prominent inventor based in Dhahran, Saudi Arabia. With two patents to his name, he has made significant contributions to the field of polymer chemistry, particularly in the development of methods for producing advanced copolymers and nanocomposites. His innovative approaches have the potential to greatly enhance material properties, paving the way for new applications in various industries.

Latest Patents

Mamdouh A Al-harthi's latest patents include a "Method of making an ethylene-propylene copolymer" and a "Method for making and using a supported zinc aluminum layered double hydroxide catalyst."

The method for the ethylene-propylene copolymer involves immobilizing a metallocene catalyst on a layered double hydroxide (LDH) to form a supported catalyst complex. This complex is mixed with a nonpolar solvent to form a first mixture, which undergoes degassing before being saturated with a gaseous mixture of ethylene and propylene. The subsequent addition of an aluminoxane catalyst initiates the polymerization reaction, resulting in the EP copolymer.

The second patent outlines a process for creating a polyolefin nanocomposite. This method includes mixing zinc-aluminum layered double hydroxide with a zirconocene complex in a nonpolar solvent, followed by sonication to achieve a homogeneous slurry. After degassing and adding olefin gas, an aluminoxane catalyst is introduced to initiate the reaction, yielding a polyolefin nanocomposite which is then separated from the reaction mixture.
