  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 (CO 2 ) 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.
