PROCESSES FOR PRODUCING POLYESTER LATEXES VIA SOLVENT-FREE EMULSIFICATION

A process for making a latex emulsion suitable for use in a toner composition includes contacting a resin with a solid neutralizing agent in the absence of an organic solvent to form a mixture either via a co-feeding process or a pre-blend mixture, and adding a solid or aqueous surfactant to the pre...

Summary:A process for making a latex emulsion suitable for use in a toner composition includes contacting a resin with a solid neutralizing agent in the absence of an organic solvent to form a mixture either via a co-feeding process or a pre-blend mixture, and adding a solid or aqueous surfactant to the pre-blend mixture or prior to melt mixing the mixture. Ci-après, un procédé pour la fabrication d'une émulsion de latex convenable pour l'utilisation dans une composition de toner. Le procédé consiste à faire entrer une résine en contact avec un agent solide de neutralisation en l'absence de solvant organique pour former un mélange (soit par l'intermédiaire d'un processus d'introduction simultanée ou le mélange d'un prémélange); et à ajouter un solide ou un agent de surface aqueux au mélange du prémélange ou à l'ajouter avant de mélanger le mélange par fusion.
