Latest Patents

One of Arai's latest patents is a paper-making process that enhances the preparation of paper from a paper stock suspension. This process involves the addition of water-swellable cationic polymer particles, optionally combined with an acrylamide polymer, to act as a retention-improving agent. The innovation improves the stability of retention even under high shearing forces during the paper-making step. Additionally, it reduces the load for recovering white water and treating wastewater, while also minimizing the abrasion of paper-making wires.

Another significant patent by Arai is related to a polymer emulsion that becomes water-swellable. This emulsion is created by mixing a specific monomer with a crosslinking agent and optionally another vinyl monomer capable of copolymerization. The resulting polymer can be made water-swellable through reactions with an acid, a salt, or a quaternizing agent.
