Latest Patents

Koji Azuma holds a patent for a novel process titled "Process for the preparation of vinyl chloride-based resins." This process involves modifying vinyl chloride-based resins with a polymer latex. The method ensures that the latex polymer is absorbed uniformly on the polyvinyl chloride resin, significantly enhancing the modification effects without adversely affecting the particle size distribution. Additionally, it prevents the effluence of latex into wastewater during the dehydration of the aqueous polymerizate slurry after polymerization. The process is characterized by introducing the modifier polymer latex when the monomer conversion is between 30% and 95%, along with an inorganic fine powder such as fume silica, bentonite, or diatomaceous earth.
