Title: Takamaro Kakehi: Innovator in Polymer Chemistry
Introduction
Takamaro Kakehi is a notable inventor based in Nagaokakyo, Japan. He has made significant contributions to the field of polymer chemistry, particularly in the development of innovative binder resin compositions and vinyl polymers. With a total of 3 patents, Kakehi's work has implications for various industrial applications.
Latest Patents
Kakehi's latest patents include a binder resin composition and an inorganic fine particle-dispersed paste composition. The binder resin composition is designed to be excellent in thixotropy and storage stability, with minimal changes in screen printability over time. It can also be fired at low temperatures. This invention comprises a binder made from a (meth)acrylic resin, an organic compound with three or more hydroxyl groups, and an organic solvent. The organic compound's content ranges from 0.1 to 15 parts by weight relative to 100 parts by weight of the (meth)acrylic resin.
Another significant patent focuses on the process for producing a vinyl polymer with a functional group at the end. This method allows for the easy and practical production of a polymer from a functional group-terminated vinyl monomer. The process involves synthesizing a halogen atom-terminated vinyl polymer through radical polymerization and subsequently introducing a functional group to the terminus by substituting a functional group-containing group for the terminal halogen atom.
