A process including mixing a slurry of HOGaPc Type I polymorph, under low shear and high flow, in an organic solvent, wherein there results a HOGaPc Type V polymorph with superior electrophotographic imaging properties.

Processes for the preparation of hydroxygallium phthalocyanine

A process for the preparation of conductive polymers which comprises (a) mixing at least one monomer with at least one conductive component, solvent, at least one polymerization initiator, and an optional chain transfer component; (b) effecting solution polymerization by heating; (c) removing said solvent by azeotropic distillation in an aqueous phase to generate a mixture of polymer and conductive component; (d) drying and grinding the resulting mixture; thereafter dissolving the product resulting in at least one monomer, at least one initiator, and at least one crosslinking component, and an optional chain transfer agent to form an organic phase; (e) mixing said organic phase with a second aqueous phase comprised of water, stabilizer, and an alkali halide; (f) polymerizing the resulting suspension by heating; and (g) subsequently optionally washing and drying the polymeric product, and which product is comprised of polymer and conductive component dispersed therein.

Conductive polymers

A suspension polymerization process for the preparation of a polymeric material formed from at least two monomers, a non-gaseous monomer and a gaseous monomer. The composition of the beads or particles of the polymeric material is controlled by adding gaseous monomer to the vapor phase after polymerization of about 5% to about 90% by weight of the non-gaseous monomer or by removing a portion or substantially all of the gaseous monomer in the vapor phase before polymerization of about 70% by weight of the gaseous monomer in the aqueous suspension, or a combination thereof.

Suspension polymerization process for the preparation of polymeric

Processes for the preparation of polymers which comprises a suspension free radical polymerization of a monomer phase comprised of at least two monomers, and a polymerization initiator; and an aqueous phase comprised of water and magnetite.

Suspension polymerization processes and toner compositions thereof

A process for the preparation of polymers which comprises forming an aqueous phase comprised of water and a surfactant; adding to the aqueous phase monomers; subsequently initiating polymerization of the monomers; thereafter adding a stabilizing component; and completing the polymerization.
