Title: Innovations of Inventor Hassam Mazhar in Ethylene-Propylene Copolymerization

Introduction

Hassam Mazhar is an accomplished inventor based in Dhahran, Saudi Arabia, with a notable portfolio that includes four patents. His inventive contributions focus primarily on advanced methodologies for polymer production, particularly in the area of ethylene-propylene copolymers.

Latest Patents

Among his latest innovations, Hassam has developed a robust method for making ethylene-propylene (EP) copolymers. This method involves immobilizing a metallocene catalyst on a layered double hydroxide (LDH) to create a supported metallocene catalyst complex. The process includes mixing this complex in a nonpolar solvent, followed by degassing the mixture and saturating it with a gaseous mixture of ethylene and propylene. Subsequently, an aluminoxane catalyst is introduced to initiate the polymerization, ultimately yielding the desired EP copolymer.

Additionally, Hassam has patented a method for making and using a supported zinc-aluminum layered double hydroxide catalyst. This method entails mixing a zinc-aluminum layered double hydroxide with a zirconocene complex, initially unsupported, in a nonpolar solvent. After sonicating the mixture to achieve homogeneity, it is treated with olefin gas and an aluminoxane catalyst to form a polyolefin nanocomposite, which is then separated from the reaction mixture.
