Title: The Innovative Contributions of Conrad Siegers
Introduction
Conrad Siegers is a notable inventor based in London, Canada. He has made significant contributions to the field of polymer science, particularly in the development of polyisoolefin copolymers. With a total of 8 patents to his name, Siegers has demonstrated a commitment to advancing technology through his innovative ideas.
Latest Patents
Among his latest patents, Siegers has developed a method for the ultrafiltration of polyisoolefin copolymers with reduced oligomer content. This method involves separating a polyisoolefin elastomer from non-polymeric components in an organic solvent using a semipermeable membrane. The process effectively retains the polyisoolefin elastomer in the retentate while allowing non-polymeric components to pass through as permeate. This innovation not only enhances the efficiency of the separation process but also ensures that stabilizers for the elastomer are retained. Additionally, Siegers has created a process for curing polyisoolefin copolymers, which reduces oligomer content to 900 ppm or less, resulting in an oligomer-depleted mixture suitable for curing with a resin cure system. Another significant invention involves phosphonium ionomers that comprise pendant vinyl groups, showcasing his expertise in polymer chemistry.
Career Highlights
Throughout his career, Siegers has worked with prominent companies such as Lanxess International SA and Lanxess Corporation. His experience in these organizations has allowed him to refine his skills and contribute to groundbreaking advancements in polymer technology.
