Abstract
Suspension stabilizer particles are removed from the surface of polymer particles formed in a limiting coalescence formation technique by dissolving in a solution containing a fluoralkyl polyether surface active agent.
Claims14
In a process of preparing electrostatographic toner by forming a suspension of polymer particles in an aqueous phase having a layer of particulate suspension stabilizer on the surface of the polymer particles, the improvement which comprises separating the particulate suspension stabilizer from the surface of the polymer particles by dissolving the suspension stabilizer in a solution containing an amount of a fluoroalkyl polyether surface active agent sufficient to prevent the agglomeration of the polymer particles freed of particulate suspension stabilizer.
