Inorganic dispersant, stabilizer for suspension polymerization and polymer particles |
摘要 |
Disclosed is an inorganic dispersant having a high specific surface area and a high surface activity which comprises a calcium phosphate type compound having a specific particle composition, particle shape, particle size and dispersibility, and specific surface area. When used as a suspension polymerization stabilizer, it provides polymer particles having a uniform and sharp particle size distribution, and when the polymer particles are contained in an unsaturated polyester resin composition and a toner composition, the obtained compositions have excellent quality.
