Latest Patents
Ohnishi's latest patents include innovative formulations for dispersing stabilizers. The first patent describes a dispersing stabilizer that consists of a polyvinyl alcohol resin containing oxyalkylene groups. This resin has a surface tension of 35 to 55 dyne/cm at 20 degrees Celsius as a 1% by weight aqueous solution. The stabilizer improves both the porosity and bulk density of polyvinyl resin particles while enhancing particle size distribution and uniformity of porosity.
The second patent focuses on a dispersing stabilizer for the suspension polymerization of vinyl compounds. This stabilizer comprises a water-soluble protective colloid and a carbonyl group-containing polyvinyl alcohol. The average degree of hydrolysis for the polyvinyl alcohol is between 10 to 90% by mole. This formulation allows for suspension polymerization of vinyl chloride without adhesion of scale to the polymerization vessel, resulting in vinyl chloride resin particles with high porosity and uniform size.
