Latest Patents

One of her latest patents is focused on a saponified ethylene-vinyl ester-based copolymer composition and its production method. The purpose of this invention is to provide an EVOH resin-based composition that maintains a desired melt viscosity without increasing the boron content, which is effective for surging prevention. This composition includes a boric acid compound that contains tetracoordinated boron. The method involves bringing an EVOH-based resin paste into contact with an aqueous solution containing a boric acid compound and alkali metal salt at elevated temperature and pressure, converting the boron to a tetracoordinated structure.

Another notable patent involves a group of pellets of ethylene-vinyl alcohol copolymer resin composition. This pellet group is designed to exhibit excellent long-run processability. The composition contains an ethylene-vinyl alcohol copolymer and a divalent metal salt, ensuring that no more than 3% of the pellets have a b*-value of not less than 5 after heat treatment at 230°C for 30 minutes.
