Title: Innovations and Contributions of Timothy A Boyer

Introduction

Timothy A Boyer is an accomplished inventor based in Eldersburg, MD (US). He holds a total of four patents, showcasing his significant contributions to the field of polymerization and catalyst technology. His work has had a profound impact on the development of efficient and effective materials.

Latest Patents

One of Boyer's latest patents is a procatalyst composition made with a combination of internal electron donors. This phthalate-free procatalyst composition is designed for olefin polymerization, exhibiting excellent polymerization activity and a strong response to hydrogen. It can produce polyolefins with 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 various internal electron donors. The first internal electron donor may include one or more substituted phenylene aromatic diesters, while the second may comprise a polyether, preferably a 1,3-diether. In one embodiment, the support precursor is a spherical spray crystallized MgCl-EtOH adduct.

Another significant patent involves the process of making aluminoxane and catalysts containing the prepared aluminoxane. This process includes bringing into contact a liquid reaction mixture in an inert atmosphere, which consists of a water-in-oil emulsion and an organoaluminum compound capable of forming aluminoxane. The aluminoxane produced is present in solution under the reaction conditions. A preferred embodiment includes a support carrier for the aluminoxane, which can be present during the contact step or introduced afterward. This process allows for the production of polymerization catalysts suitable for olefins such as ethylene or for copolymerizing olefins with at least one C to C alpha-olefin.
