  • Crystalline wax
    Publication number: 20070131580
    Abstract: Embodiments include a fractionated and/or distilled wax having from about 30 to about 64 carbon units, a degree of crystallinity as calculated by heat of melting and as measured by DSC of from about 55 to about 100, a Mw is from about 500 to about 800, and a polydispersity of from about 1 to about 1.05.
    Type: Application
    Filed: November 14, 2005
    Publication date: June 14, 2007

  • Crystalline wax
    Publication number: 20070108097
    Abstract: Embodiments include a distilled wax having a crystallinity of from about 55 to about 100 percent, wherein the degree of crystallinity is calculated using the following formulas: [Heat of enthalpy (Hm) J/g/294 J/g]×100=degree of crystallinity (Xc); [Heat of recrystallization (Hrc) J/g/294 J/g]×100=degree of crystallinity (Xc); and Sc/(Sc+Sa)]×100%, wherein Sc is a diffraction peak area of a crystalline component of the wax and the Sa is a diffraction peak area of an amorphous component of the wax; and wherein the Mp, Mn and Mw of the wax are all within the range of from about 500 to about 800, and wherein the wax has a polydispersity of from about 1 to about 1.05.

  • Toner having crystalline wax
    Publication number: 20070111131
    Abstract: Embodiments include a toner with a distilled wax having a crystallinity of from about 55 to about 100 percent, wherein the degree of crystallinity is calculated using the following formulas: [Heat of enthalpy (Hm) J/g/294 J/g]×100 =degree of crystallinity (Xc); [Heat of recrystallization (Hrc) J/g/294 J/g]×100 =degree of crystallinity (Xc); and Sc/(Sc+Sa)]×100%, wherein Sc is a diffraction peak area of a crystalline component of the wax and the Sa is a diffraction peak area of an amorphous component of the wax; and wherein the Mp, Mn and Mw of the wax are all within the range of from about 500 to about 800, and wherein the wax has a polydispersity of from about 1 to about 1.05.
