Bifunctional macromolecules and toner compositions therefrom

A process for the preparation of branched thermoplastic resins comprising: heating a mixture of an unsaturated resin, a free radical initiator, and a stable free radical agent; adding to the heated mixture at least on polymerizable monomer; and cooling the mixture, wherein the resulting product is a branched thermoplastic resin with arms or branches comprised of polymerized monomer with substantially uniform length and narrow polydispersity.

Processes for the preparation of branched polymers

A polymer having groups located at the ends of the polymer chain which groups are derived from stable free radical compounds, wherein the polymer is of the formula:
