With a total of 11 patents to his name, Shiotani's work has had a substantial impact on various industrial applications.
Latest Patents
One of Shiotani's latest innovations is a polyimide/metal composite sheet. This composite is composed of a metal film and a polyimide film, which is prepared through the reaction of asymmetric biphenyltetracarboxylic acid dianhydride and 1,3-bis(4-aminophenoxy)benzene. The unique feature of this composite is that the polyimide film is firmly bonded to the metal film, making it difficult to peel apart. Additionally, the polyimide film can contain a solid filler, enhancing its properties for various applications.
Another notable patent involves a process for producing polycarbonate. In this process, a diaryl carbonate is produced by decarbonylating a diaryl oxalate, which can be prepared by transesterification of a dialkyl oxalate with a hydroxyaryl compound. This reaction occurs in the presence of a catalyst while removing the resultant carbon monoxide as a by-product. The resulting diaryl carbonate is then condensation-polymerized with a polyhydroxyl compound, allowing for the recovery of a hydroxyaryl compound from the reaction system to produce polycarbonate.
