Title: **Michio Yamaura: Innovator in Optical Films**
Introduction
Michio Yamaura, an esteemed inventor based in Hachioji, Japan, has made significant contributions to the field of optical materials. With a total of six patents to his name, his innovative work focuses primarily on advanced polymer films and their applications in optics.
Latest Patents
Among his latest inventions is a pioneering optical film comprised of a single polymer that exhibits a minimized phase difference as the wavelength shortens. This film is crafted from an olefin-based polymer featuring an alicyclic group in its side chain. This specific formulation, where the alicyclic group's content ranges from 60 to 90 wt % of the total polymer, successfully meets the criteria specified by the phase difference expressions at wavelengths of 450 nm and 550 nm.
Additionally, Yamaura has developed a cyclic olefin polymer characterized by low catalyst residue. This innovation includes a production process for the cyclic olefin polymer, which involves efficiently decomposing catalysts utilized during polymerization or hydrogenation. This process is enhanced by the incorporation of specific compounds, leading to effective removal of the catalyst residues, rendering them insoluble and precipitating them out of the reaction solvent.
