Latest Patents

Koga's latest patents include a method for the preparation of matte vinyl chloride polymer and a composition thereof. This innovative process involves suspension polymerizing a monomeric charge that includes vinyl chloride in an aqueous medium. The polymerization is initiated in the presence of diallyl phthalate, and the resulting matte vinyl chloride-diallyl phthalate copolymer exhibits a tetrahydrofuran-insoluble gel content of 0.5-2.5% by weight. Additionally, Koga has developed a method for preparing powder that includes adding a fluoro non-ionic surfactant. This method allows for the production of vinyl chloride polymer powder that remains electrically neutral during storage and transport, thus maintaining its bulk density and flow properties.
