Processes for aquabulk polymerization to produce high purity toners

摘要

A surfactant stabilizer free heat transfer bulk polymerization process for the preparation of a polymer or polymers which comprises adding water to a reaction vessel; heating the reaction vessel; adding to the reaction vessel a solution of monomer or monomers and initiators; heating the reaction vessel contents; increasing the temperature in the reaction vessel to from between about 95 DEG to about 105 DEG C. thereby removing water therefrom; and subsequently further heating the vessel contents to an effective temperature to enable said polymer or said polymers.
