Title: Innovations of Shinji Inaba
Introduction
Shinji Inaba is a notable inventor based in Kawasaki, Japan. He has made significant contributions to the field of materials science, particularly in the development of advanced resin compositions and block copolymers. With a total of 3 patents, his work has implications for various industrial applications.
Latest Patents
One of his latest patents is for an insulating resin composition and laminate obtained therefrom. This invention relates to a resin composition that exhibits high impact resistance and heat resistance, along with good adhesiveness to plating metals. It is selectively etchable by permanganate salts commonly used in plating operations, making it suitable for insulating layers in multilayer wiring boards. The composition includes a crosslinked elastic polymer that has carboxyl groups and is dispersed with an average secondary particle diameter ranging from 0.5 to 2 micrometers.
Another significant patent by Inaba is a process for preparing aromatic polyester-polystyrene block copolymers. This process involves the condensation of styrene polymers with terminal functional groups and an excess of aromatic dicarboxylic acid dihalides. The resultant block copolymers contain a small amount of uncopolymerized styrene polymers and exhibit desirable properties such as low birefringence, good transparency, and excellent mechanical strength. These materials are particularly useful in optical instruments.
