    摘要： A process for the preparation of a latex polymer by (i) preparing or providing a water aqueous phase containing an anionic surfactant in an optional amount of less than or equal to about 20 percent by weight of the total amount of anionic surfactant used in forming the latex polymer; (ii) preparing or providing a monomer emulsion in water which emulsion contains an anionic surfactant; (iii) adding about 50 percent or less of said monomer emulsion to said aqueous phase to thereby initiate seed polymerization and to form a seed polymer, said aqueous phase containing a free radical initiator; and (iv) adding the remaining percent of said monomer emulsion to the composition of (iii) and heating to complete an emulsion polymerization thus forming a latex polymer.

    摘要： A process for making toner particles is provided. In embodiments, a suitable process includes melt mixing a resin in the absence of an organic solvent, optionally adding a surfactant to the resin, adding to the resin at least one colorant and other optional toner additives, adding to the resin a basic agent and water to form a mixture, and subjecting the mixture to acoustic mixing at a suitable frequency to form to form an emulsion. A phase inversion may then be performed to create a phase inversed emulsion including a disperse phase comprising molten resin and the optional ingredients of the toner composition, at which time toner-sized droplets may be solidified from the disperse phase into toner particles, which can be recovered for use.

    摘要： A latex used for the preparation of toner particles by emulsion aggregation is prepared, using a controlled addition of anionic surfactants, without the use of a nonionic surfactant. Such a process comprises preparing an aqueous phase using a limited amount of anionic surfactant; preparing an emulsion of monomers in water with additional anionic surfactant and without a nonionic surfactant; adding a portion of the emulsion to the aqueous phase to initiate seed polymerization, in the presence of an initiator, to form seed polymer; and adding the remaining monomer emulsion to the composition to complete polymerization to form a latex polymer.
