A toner composition and processes for the preparation thereof comprising the steps of: (i) preparing a latex emulsion by agitating in water a mixture of a nonionic surfactant, an anionic surfactant, a first nonpolar olefinic monomer, a second nonpolar diolefinic monomer, a free radical initiator and a chain transfer agent; (ii) polymerizing the latex emulsion mixture by heating from ambient temperature to about 80.degree. C. to form nonpolar olefinic emulsion resin particles of volume average diameter from about 5 nanometers to about 500 nanometers; (iii) diluting the nonpolar olefinic emulsion resin particle mixture with water; (iv) adding to the diluted resin particle mixture a colorant or pigment particles and optionally dispersing the resulting mixture with a homogenizer; (v) adding a cationic surfactant to flocculate the colorant or pigment particles to the surface of the emulsion resin particles; (vi) homogenizing the flocculated mixture at high shear to form statically bound aggregated composite particles with a volume average diameter of less than or equal to about 5 microns; (vii) heating the statically bound aggregate composite particles to form nonpolar toner sized particles; (viii) optionally halogenating the nonpolar toner sized particles to form nonpolar toner sized particles having a halopolymer resin outer surface or encapsulating shell; and (ix) isolating the nonpolar toner sized composite particles.
