Title: Hikoichiro Yamada: Innovator in Metathesis Polymer Technology
Introduction
Hikoichiro Yamada is a notable inventor based in Iwakuni, Japan. He has made significant contributions to the field of polymer science, particularly in metathesis polymerization. With a total of two patents to his name, Yamada's work has advanced the understanding and application of polymer materials.
Latest Patents
Yamada's latest patents include a process for making a filled metathesis polymer article. This innovative method involves the metathesis polymerization of a mixture that contains at least one metathesis polymerizable monomer, a catalyst, and a treated filler material. The filler is treated with a vinyl-substituted silane coupler, enhancing the properties of the molded article. Another significant patent is for a molded polymer article filled with inorganic material. This method prepares filled shaped articles of metathesis polymerized poly(cycloolefins) by treating an inorganic filler with a norbornene-substituted silane coupling agent. This approach not only copolymerizes with the metathesis polymerizable monomer but also creates a strong bond with the filler, resulting in products with improved physical properties.
