Abstract

A bimodal, crosslinked toner resin can be prepared in non-aqueous solvent, e.g., toluene, using standard solution polymerization techniques. The resin-forming process prepares a precursor resin from ethylenically unsaturated monomer(s), and then grafts malefic anhydride onto the precursor resin to form a modified precursor resin. The modified precursor resin is reacted with a polyfunctional molecule, e.g. a diol, to provide a crosslinked resin. The process is preferably conducted in the presence of a low molecular weight polymeric additive, e.g., polystyrene, to provide a bimodal as well as crosslinked toner resin composition. With the addition of a colorant, a toner powder may be formed.
