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.
