In this study, the copolymerization of a novel macromonomer, styrene and n-butyl acrylate was investigated to produce toner latexes that are very stable, and their particles are uniform and monodisperse without using any stabilizers or surfactants. Macromonomers are a relatively new category of functionalized polymer materials having one or more polymerizable end groups, thus the use of macromonomers provides an alternative route to stabilize polymer colloids in replacement of surfactants or steric stabilizers in radical polymerizations. Macromonomers acts not only as a stabilizer but also as a comonomer during the polymerization. This toner process is a simple, economical and environmentally friendly process by reducing the amount of wasting water in the washing step due to the surfactant-free process. The size and shape of the toner can be controlled through a selection of the process temperature and the heating time or through a control of the glass transition temperature and the molecular weight of the latexes. The properties of the chemically prepared toner and the results of the printing test are appeared in the presentation.
