Haruyuki Minoura is a distinguished inventor based in Kurashiki, Japan. He has made significant contributions to the field of polymer chemistry, holding a total of 3 patents. His innovative work focuses on the development of advanced copolymers and methods for their production.

Latest Patents

One of Minoura's latest patents is for an oxytetramethylene glycol copolymer and the method for producing it. This copolymer is synthesized by copolymerizing tetrahydrofuran and neopentyl glycol, resulting in a product with specific molecular characteristics. The patent also details a purification method that involves adding fresh tetrahydrofuran to a reaction mixture containing the copolymer and unreacted diol, followed by distillation to remove the unreacted diol.

Another notable patent involves a method for acylating hexakis (arylmethyl) hexaazaisowurtzitane. This method enhances the acylation process by reductively removing arylmethyl groups in the presence of an acylating agent. The innovative approach prevents the decomposition of the hexaazaisowurtzitane skeleton, allowing for stable production of tetraacylhexaazaisowurtzitane derivatives in high yields.
