Title: Tarja Soderberg: Innovator in Polymerization Technology
Introduction
Tarja Soderberg is a notable inventor based in Porvoo, Finland. She has made significant contributions to the field of polymerization, particularly through her innovative catalyst systems. With a total of 2 patents, her work has advanced the understanding and application of olefin polymerization.
Latest Patents
Soderberg's latest patents include a stereospecific catalyst system for the polymerization of olefins. This invention allows for the polymerization of olefins, especially propene and mixtures of propene with ethene, using a Ziegler-Natta catalyst system. The catalyst system incorporates a transition-metal-based procatalyst and cocatalyst, along with an external donor that enhances the stereospecificity of the produced polymer. By utilizing an acetal derivative of an aldehyde with two ether groups, Soderberg's method achieves high stereospecificity and allows for easy control of the molecular weight of the product through hydrogen as a chain transfer agent.
Another significant patent involves a process for the gas-phase homo- or copolymerization of alpha-olefins. This innovative process addresses the challenge of product agglomeration during polymerization. By pretreating the catalyst system with a transition-metal compound and an organoaluminum compound in a liquid medium, Soderberg has developed a method that prevents agglomeration, thus improving the handling of the polymer product.
