Title: Kouji Katoh: Innovator in Water-Absorbing Composites
Introduction
Kouji Katoh is a notable inventor based in Yokkaichi, Japan. He has made significant contributions to the field of water-absorbing composites, holding a total of 2 patents. His work focuses on innovative methods for producing materials that excel in water absorption and retention.
Latest Patents
One of Kouji Katoh's latest patents is a continuous production method of water-absorbing composite. This invention outlines a complexation step that involves producing a particle-substrate composite by dropwise supplying an aqueous solution of polymerizable monomers. These monomers primarily consist of an unsaturated carboxylic acid, where 20% or more of the carboxyl groups are neutralized. The process allows polymerization to proceed in the droplets onto a fibrous substrate, enabling incompletely polymerized polymer particles to adhere. The polymerization is completed thereafter, resulting in a composite that is efficient in water absorption and retention properties.
Another significant patent involves the preparation processes of water-absorbing composites and the resulting water-absorbing articles. This work further emphasizes the efficiency and effectiveness of the production methods developed by Katoh.
