Title: Innovations by Harald Jacobsen: Advancements in Composite Materials

Introduction

Harald Jacobsen, an inventive mind based in Stathelle, Norway, has made significant contributions to the field of composite materials. With two patents to his name, Jacobsen's work focuses on innovative methods of production and material development, shaping the future of polymer technology.

Latest Patents

Jacobsen's latest patents include a revolutionary method of making a composite material through paste polymerization. This process involves forming an emulsion of at least one polymerizable monomer in an aqueous medium, polymerizing this emulsion to create a latex containing polymer particles. Notably, the polymer exhibits a glass transition temperature above 65 °C. The method also integrates nanoparticles—ranging from 0.5 to 200 nm in at least one dimension—culminating in a spray-drying technique that enhances material properties.

The second patent details a two-stage seed swelling procedure for producing monodisperse PVC particles. This innovative approach allows for the creation of PVC particles with a narrow size distribution, specifically in the 10-50 µm range, and preferably 10-30 µm. In the first stage, a vinyl monomer undergoes polymerization to form small polymer/oligomer seed particles between 1-10 µm. The second stage leverages the swelling of these seed particles using another vinyl monomer, resulting in the growth of these particles to the desired dimensions. The methodology emphasizes the use of aromatic vinyl monomers or acrylates for optimal results.

Career Highlights

Throughout his career, Jacobsen has worked with prominent companies, notably Hydro ASA and Ineos Norge Holdings AS. His work in these organizations has not only honed his expertise but also provided him with the platform to execute his innovative ideas in the realm of polymer technology.
