Title: Yasuhiro Moriuchi: Innovator in Polymer Chemistry
Introduction
Yasuhiro Moriuchi is a notable inventor based in Niihama, Japan. He has made significant contributions to the field of polymer chemistry, particularly in the development of innovative materials. With a total of 3 patents, his work has had a considerable impact on various applications.
Latest Patents
Moriuchi's latest patents include a groundbreaking block copolymer. This block copolymer consists of poly(N-formylethyleneimine) or poly(N-acetylethyleneimine) combined with poly(N-acylethyleneimine) or poly(N-acylpropyleneimine), featuring a molecular weight ranging from 500 to 50,000. These materials are particularly useful as surface-active agents. Another significant patent involves a vinyl chloride type resin composition. This composition includes 100 parts by weight of a vinyl chloride type resin and 25 to 200 parts by weight of a plasticizer. The resin is composed of 1 to 90% by weight of a tetrahydrofuran-insoluble gel fraction, with the remainder being a tetrahydrofuran-soluble fraction. This innovative composition results in a rubbery elastomer that exhibits excellent heat deformation resistance, a superior matt finish, and a minimal compression permanent set. Although it closely resembles rubber in properties, it maintains moldability and processability akin to conventional thermoplastic resins, making it suitable for applications such as automotive interior materials, packing, and tubing.
