Polymerization process for the preparation of a resin

Polymerization processes

A free radical polymerization process for the preparation of a thermoplastic resin or resins includes the in situ formation of a stable free radical agent from a precursor material in a reactor vessel, introducing a free radical initiator and at least one polymerizable monomer compound into the reactor vessel, and heating a mixture of the free radical initiator, the stable free radical agent, and the polymerizable monomer compound(s) in the reactor vessel to form a thermoplastic resin.

Process for producing thermoplastic resin polymers

Bifunctional macromolecules and toner compositions therefrom

A process for the preparation of polymer comprising heating a mixture comprised of a free radical initiator, a stable free radical agent, a base selected from the group consisting of inorganic bases and organic bases, and at least one polymerizable monomer compound and optionally cooling, followed by optionally isolating the polymer product.

Stable free radical polymerization processes

A process for the preparation of a thermoplastic resin, or thermoplastic resins comprising:

Polymerization processes using oligomeric compound, monomer and

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 process for the preparation of resin particles comprising: heating a mixture comprised of a free radical initiator compound, at least one stable free radical compound, at least one free radical polymerizable monomer compound, and at least one free radical polymerizable crosslinking compound; and cooling the mixture, wherein the resulting product resin particles are crosslinked and are comprised of polymerized monomers and at least one crosslinking compound, and wherein the particles have a narrow particle size distribution, a narrow pore size distribution, and a high monomer to polymer conversion.
