摘要: Amorphous polyester resins and processes for making the same are disclosed herein. In particular, the process for making the resin provides resins with improved properties. The amorphous polyester resins have substantially reduced free fumaric acid as compared to that made from conventional processes. The toner resins are used to prepare toner compositions the have improved performance.

摘要: A process includes forming, by emulsion polymerization, polymer resin particles in a latex, the polymer resin particles being formed from a mixture including one or more monomer emulsions and a non-surfactant-based charge control agent, the emulsion polymerization is carried out with a solids content in a range from about 10 to about 30 percent by weight of the mixture, and forming toner particles from the polymer resin particles, the toner particles support a sufficient triboelectric charge for use under A-zone environmental conditions in a single-component development system.

摘要: Incorporation of organic amines as neutralization agents in based phase inversion emulsification (PIE) processes to provide emulsification of high molecular amorphous and high molecular branch amorphous polyester resins, which are traditionally difficult to emulsify. The organic amines facilitate emulsification of these resins to achieve desired particle size with a narrow size distribution.
