Patent ID: 8257899

Claim:
A toner process comprising consisting of: reacting an organic diol selected from the group consisting of 1,2-propanediol, 1,3-propanediol, 1,3-butane diol, pentylene glycol, hexylene glycol, diphenol, neopentyl glycol, diethylene glycol, dipropylene glycol, 2,2-bis-(4-hydroxy phenyl)propane, 2,2-bis-(3-hydroxy phenyl)propane, 2,2-bis-(2-hydroxy phenyl)propane, 2,2-bis-(3-hydroxy phenyl)propane, 2,2-bis-(5-hydroxy phenyl)propane, Bisphenol-A, ethoxylated Bisphenol-A, bis-(4-hydroxy phenyl)methane, 1,1-bis-(4-hydroxy phenyl)ethane, cis-1,4-dihydroxy-cyclohexane, trans-1,4-dihydroxy-cyclohexane, cis-1,2-dihydroxy-cyclohexane, trans-1,2-dihydroxy-cyclohexane, trans-1,3-dihydroxy-cyclohexane, cis-1,3-dihydroxy-cyclohexane, and mixtures thereof, with a cyclic alkylene carbonate selected from the group consisting of ethylene carbonate, propylene carbonate, butylene carbonate, and mixtures thereof, in the presence of a first catalyst of an alkali carbonate to form a polyalkoxy diol; contacting the polyalkoxy diol with an additional amount of cyclic alkylene carbonate in the presence of a second catalyst of an alkali alkoxide to form a mixture; polycondensing the resulting mixture with a dicarboxylic acid and an anhydride selected from the group consisting of n dodecenylsuccinic anhydride, 2-dodecenylsuccinic anhydride, 2-undecenylsuccinic anhydride, and mixtures thereof; recovering an unsaturated polyester; contacting the unsaturated polyester with a colorant, a surfactant, and a wax to form small particles; aggregating the small particles; coalescing the small particles to form toner particles; and recovering the toner particles.
