    摘要： The present invention is a method of making a stable colloidal non-aqueous wax particle dispersion. The method includes the steps of forming a mixture of a first vinyl monomer of a polymerizable mono-alpha, beta-ethylenically unsaturated compound free of ionic charge groups and capable of addition polymerization and a second vinyl monomer capable of addition polymerization and wax particle in a aqueous medum. The mixture is polymerized using an azo or diazo initiator to form an aqueous dispersion of composite wax particles. The wax particles are redispersed in an organic solvent.
