Latest Patents
Yamamoto's latest patents focus on innovative processes for producing vinyl chloride polymers. One of his patents describes a method for producing vinyl chloride polymer in the presence of a chelating agent. This process allows for the polymerization of vinyl chloride or a monomer mixture in an aqueous medium using a polymerization initiator. The inclusion of a chelating agent capable of binding iron (II) and iron (III) helps prevent polymer scales from adhering to the inner walls of the polymerization vessel. This advancement not only improves the quality of the final product by reducing discoloration but also enhances the efficiency of the polymerization process.
Another patent by Yamamoto outlines a similar process for producing vinyl chloride polymer, emphasizing the importance of using a polymerization vessel that has been treated with a polymer scale preventive agent. This treatment further ensures that the polymer scales do not adhere to critical surfaces during production, thereby improving the overall quality of the polymer products.
