Abstract: método para obter cera a partir de polietileno reciclado. um método econômico e ambientalmente conveniente para produzir ceras. em particular os métodos usam degradação termolítica simultaneamente com um processo de destilação para obter ceras destiladas a partir de polietileno reciclado. as ceras resultantes possuem propriedades desejáveis, tais como reduzido peso molecular e baixa polidispersão, o que torna as ceras úteis em várias aplicações

Abstract: The present disclosure provides polyesters suitable for use in forming toners. In embodiments, a polyester may be subjected to phase inversion emulsification, in which charge control agents are added so that the polyester emulsion includes charge control agents therein. The resulting polyester emulsion with charge control agents may then be utilized to form toner particles.

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] x 100 = degree of crystallinity (Xc); [Heat of recrystallization (Hrc) J/g / 294 J/g] x 100 = degree of crystallinity (Xc); and Sc/(Sc+Sa)] x 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.

Abstract: The present disclosure provides processes for reducing the particle size of latex resins and toners produced with such resins. In embodiments, a carboxylic acid may be added to materials utilized to produce a latex and reduce the particle size of the resulting latex particles and toner particles. In accordance with the present disclosure, one may be able to utilize materials for the production of latex resins and toners which may otherwise produce particles that are too large in the absence of the carboxylic acid.
