Introduction

Na Zhao is a prominent inventor based in Shandong, China, known for his contributions to the field of organic silicon polymer material preparation. With a total of two patents to his name, Zhao has made significant advancements in the continuous production of high-molecular-weight polysiloxanes.

Latest Patents

One of Zhao's latest patents is a "Continuous production device for organophosphorus nitrile-catalyzed high-molecular-weight polysiloxane." This invention features a reaction device with a horizontal configuration and dual-axis stirring. The design allows for a gradual decrease in the diameters of the dual axes from the feed port to the discharge outlet, while the nominal diameters of the paddles increase correspondingly. The stirring shaft and paddles are hollow, enabling external heating or cooling. This innovative device enhances mass transfer, heat transfer, and axial propelling force, resulting in uniform products with a narrow molecular weight distribution and low volatile content. It is particularly effective for the continuous production of high-viscosity, high-molecular-weight polysiloxanes catalyzed by organophosphorus nitrile.

Another notable patent is for a "Phosphazene compound, preparation method and use thereof." This patent provides a phosphazene compound and outlines methods for its preparation and for producing a polymer using the phosphazene compound as a catalyst. The compound features a six- or eight-membered ring consisting of repeated P=N units, with various substituents that enhance its utility in chemical processes.
