Title: Michael Lederer: Innovator in Polymerization Processes
Introduction
Michael Lederer is a notable inventor based in Falkenstein, Germany. He has made significant contributions to the field of polymer chemistry, particularly in the area of suspension polymerization. With a total of 3 patents to his name, Lederer continues to push the boundaries of innovation in his field.
Latest Patents
One of Lederer's latest patents focuses on an improved process for the discontinuous suspension polymerization of alkenyl-aromatic compounds. This process involves re-using the aqueous polymerization medium after the separation of polymer beads, which allows for a more sustainable approach to polymer production. The addition of monomer-soluble and water-soluble initiators, along with fresh water and dispersing agents, does not negatively impact the color and mechanical properties of the resulting polymer. This innovative method results in considerable energy savings.
Another significant patent by Lederer describes a process for preparing impact-resistant polyvinyl aromatics. This improved bulk-suspension process polymerizes vinyl aromatic monomers in the presence of ethylene-propylene-nonconjugated diene-rubber. By using peroxy-carbonic esters as the polymerization initiator, the process yields products with enhanced notched impact strength, weatherability, and elongation at break, while maintaining good shear stability.
