Estimating the term…
A toner composition includes a styrene/butadiene resin having a weight average molecular weight of less than about 70,000 and a number average molecular weight of from about 8,000 to about 12,000, has a glass transition temperature of from about 50.degree. C. to about 60.degree. C. and provides excellent gloss and high fix properties at a low fusing temperature. The styrene/butadiene resin is produced by an emulsion polymerization process that includes forming an emulsion of a surfactant, styrene monomer, butadiene monomer and a water-soluble monomer in water, and then polymerizing the monomers in the presence of a water-soluble initiator.
A toner composition comprising a polymer resin and a colorant, wherein said resin comprises styrene, butadiene, and a water-soluble monomer and has a weight average molecular weight of less than about 70,000, a number average molecular weight of from about 8,000 to about 12,000, and a glass transition temperature of from about 50.degree. C. to about 60.degree. C.
