    摘要： Disclosed is a process which comprises (a) reacting allyl bromide with diethyl amine in a molar ratio of at least about 1 mole of allyl bromide per about 1.15 moles of diethyl amine and in a molar ratio of no more than about 1 mole of allyl bromide per about 2 moles of diethyl amine, thereby generating allyl diethyl amine in a monomer reaction mixture; (b) subsequently filtering the monomer reaction mixture to remove impurities; (c) subsequently reacting the allyl diethyl amine with allyl bromide, thereby generating solid diallyl diethyl ammonium bromide; (d) subsequently isolating the solid diallyl diethyl ammonium bromide; (e) subsequently dissolving the diallyl diethyl ammonium bromide in a solvent and adding thereto a polymerization initiator to form a polymerization reaction mixture; (f) subsequently heating the polymerization reaction mixture in a vessel equipped with a reflux condenser to a temperature of from about 90 to about 100° C., thereby generating poly(diallyl diethyl ammonium bromide); and (g) subsequently optionally isolating the poly(diallyl diethyl ammonium bromide) from the polymerization reaction mixture.

    摘要： A process for the preparation of a latex polymer consistent with E/A (emulsion/aggregation/coalescence) toner manufacture. The process utilizes a standard (universal) latex composition and involves chain-transfer agent partitioning, emulsion polymerization that provides a latex polymer with a wide range of molecular properties. In particular, the process customizes a wide range Mw (weight average molecular weight) latex, without substantially varying the Mn (number average molecular weight) and hence, without substantially varying Tg (glass transition temperature) such that good toner performance is maintained. In a preferred process, a latex polymer is prepared by mixing a seed particle latex, generated by aqueous emulsion polymerization of a first portion of a monomer emulsion, with a second portion of the monomer emulsion and at least one chain-transfer agent. The mixing is done in the presence of a free-radical initiator and heated, and wherein the monomer emulsion comprises a mixture of polymerization reagents of at least one monomer, at least one chain-transfer agent, at least one surfactant, and water. This process may be applied to core-shell polymerization as well. These latex polymers are ideally suited in the manufacture of toner and developer for electrophotographic imaging and printing.

    摘要： A one-step polymerization process for producing a bimodal resin having a distinct low molecular weight portion and a high molecular weight portion includes initiating an anionic polymerization of a monomer or monomers to produce living polymer chains, terminating a portion of the living polymer chains, and completing the polymerization of the remaining living polymer chains. The bimodal resin is useful, for example, in high gloss, low melt toner applications.
