Title: Innovations of Thomas J Pullukat
Introduction
Thomas J Pullukat is a notable inventor based in Lansdale, PA (US). He has made significant contributions to the field of polymerization catalysts, holding a total of four patents. His work focuses on enhancing the efficiency and effectiveness of catalysts used in olefin polymerization processes.
Latest Patents
One of his latest patents involves high activity olefin polymerization catalysts. This method for preparing a silica-supported α-olefin polymerization catalyst includes treating a silica support with an organosilane compound, followed by contacting it with a transition metal compound to form an intermediate. The process continues with the introduction of an alkylmagnesium alkoxide to create the catalyst. The transition metal compound can be a metal chloride or a metal chloroalkoxide, with the transition metal being selected from titanium, vanadium, and zirconium. The alkylmagnesium alkoxide may include various compounds such as butylethylmagnesium butoxide or butylmagnesium propoxide. This innovative process results in catalysts with higher activities compared to those prepared by traditional methods.
Another significant patent by Pullukat focuses on olefin polymerization catalysts with specific silica supports. This catalyst features a high pore volume and high surface area porous silica support, combined with a non-metallocene, Ziegler-Natta catalytic component. The porous silica support consists of silica gel particles with an average surface area of about 600 to 800 m²/g and an average pore volume of about 2.5 to 4.0 ml/g. This invention aims to improve the production of polyolefins from α-olefins.
