Title: The Innovations of Ryuuji Sakashita
Introduction
Ryuuji Sakashita is a notable inventor based in Tokyo, Japan. He has made significant contributions to the field of polymer technology, particularly in the production of acrylic sheets. With a total of two patents to his name, Sakashita's work exemplifies innovation in material science.
Latest Patents
Sakashita's latest patents focus on a process for producing solvent-free acrylic sheets. This innovative process includes a coating step that may involve either coating at least one support with a solvent-free syrupy composition for coating polymerization or applying the syrupy composition between at least two supports at a coating thickness of at least 0.15 mm to form a laminate. The solvent-free coating polymerization syrupy composition consists of an acrylic vinyl monomer capable of radical polymerization. The process further includes a heating polymerization step, where the laminate is heated at 60 degrees Celsius or higher to initiate the reaction, inducing autoexotherm to cause the acrylic vinyl monomer to polymerize. The process concludes with an aging polymerization step, maintaining the laminate at a temperature that is at least 30 degrees Celsius but lower than the heating temperature, allowing the polymerization reaction to continue until the content of residual monomer in the laminate is 2% by weight or less.
