Title: Gary W Richie, Deceased: Innovator in Asymmetric Radial Polymers
Introduction
Gary W Richie was a notable inventor known for his contributions to the field of polymer science. He was based in Columbus, TX (US) and held a patent that significantly advanced the preparation of asymmetric radial polymers. His innovative methods have had a lasting impact on the industry.
Latest Patents
Gary W Richie was awarded a patent for a "Method for preparing asymmetric radial polymers." This method involves contacting different polymeric arms sequentially with a nonpolymerizable coupling agent. The final step of the process is carried out in the presence of a polar compound, which enhances the vinyl content in a conjugated diolefin polymer during polymerization. This method effectively narrows the relative arm distribution of the asymmetric radial polymers produced and increases the total product with the desired ratio of polymeric arms in a relatively short reaction time. The patent highlights the use of nonpolymerizable coupling agents with 3 to 12 functional groups, with those having 2 or 3 functional groups being most preferred. Useful polar compounds include ethers, tertiary amines, pyridine, and pyrolidene compounds.
