    摘要: Processes for preparing polyester resins as toner production components. The processes include reacting an organic diol and a cyclic alkylene carbonate to produce carbon dioxide (CO2) and a polyalkoxy diol. The carbon dioxide is reacted with an alkylene glycol or alkylene oxide to produce additional cyclic alkylene carbonate having the same chemical structure as the cyclic alkylene carbonate used to produce the polyalkoxy diol. The additional cyclic alkylene carbonate is added with the cyclic alkylene carbonate used to produce the polyalkoxy diol. The polyalkoxy diol can be reacted with an organic diacid or diester in preparing a polyester resin. To prepare a toner, the polyester resin can be contacted with at least one toner production component.

    摘要: A process for preparing a toner includes forming an emulsion with a buffer solution and an amorphous biodegradable polyester resin represented by Formula (1): wherein each n independently represents an integer of 1 to about 20 and x and y represent respective ratios of respective monomeric units and x ranges from about 0 to about 1000 and y ranges from about 0 to about 300; adding a colorant, a coagulant, and optionally a wax to the emulsion to form a mixture; heating the mixture, permitting aggregation and coalescence of the mixture to form toner particles; and recovering the toner particles.
