    摘要： The present invention is a process for making an electrophotographic toner binder. The toner binder has reduced mercaptan odor at elevated temperatures. The toner binder is formed by mixing monomers in a ratio that determines the final composition of the polymer or toner binder and contacting the monomers with air or oxygen. A chain transfer agent and polymerization initiator are added to the monomers. A suitable suspension polymerization type aqueous phase is prepared. The aqueous and monomer phases are blended and sheared to form monomer droplets, the mixture is suspension polymerized by heating and the aqueous phase is removed from the polymer beads.
