Title: Inventor Spotlight on Masao Maruyama
Introduction
Masao Maruyama, based in Annaka, Japan, is a notable inventor with a total of seven patents to his name. His contributions to the field of organosiloxane polymers showcase his innovative spirit and commitment to advancing technology in the chemical industry.
Latest Patents
Among his latest achievements, Maruyama has developed methods for the preparation of linear organosiloxane polymers. This process involves reacting two types of organosiloxane compounds in the presence of an alkaline compound while maintaining conditions that minimize equilibration reactions. As a result, a linear organosiloxane polymer with a single peak molecular weight distribution is produced simply and economically, with reduced formation of cyclics.
Additionally, Maruyama has pioneered a method for reactivating sulfonated resin catalysts that have lost their activity during the polymerization of silicone oil. This innovative technique involves washing the catalyst with a low molecular weight siloxane medium, followed by volatilizing the siloxane medium under atmospheric or reduced pressure, ultimately leading to the removal of water from the catalyst.
