Abstract: A method of making a composite feed material for fused deposition modeling (FDM) is disclosed. The method comprises providing composite particles made by a process of emulsion aggregation, the composite particles comprising at least one thermoplastic polymer and at least one carbon particle material. A composite feed material is formed for fused deposition modeling from the composite particles. The composite feed material is in a form selected from a filament and a paste.

Abstract: A continuous emulsion aggregation process for the production of particles is presented including a plurality of continuous stirred-tank reactors (CSTR). The plurality of continuous stirred-tank reactors includes at least one feed tank of raw materials, at least one reactor for facilitating cold addition, at least two reactors for facilitating an aggregation process, at least one reactor for facilitating a shell addition process; at least one reactor for facilitating a freeze process, at least one reactor for facilitating a chelating process, at least one reactor for facilitating a ramp-up process and at least one reactor for facilitating a coalescence process, wherein the reactors are sequentially assembled in a series configuration and separated by short conduits to produce toner particles that are narrowly distributed.

Abstract: Un proceso para producir una emulsión del látex adecuada para usarse en una composición de pigmento orgánico incluye coemulsificar una biorresina con un componente insoluble, como un pigmento o cera, por lo que la resina encapsula el componente insoluble. El látex resultante, incluyendo los componentes insolubles encapsulados en la resina, puede entonces ser utilizado para formar un pigmento orgánico. El componente insoluble puede de este modo ser incluido en partículas de pigmento orgánico, lo cual en otras circunstancias podría ser difícil de lograr usando procesos de agregación en emulsión.

Abstract: A process for making a latex emulsion suitable for use in a toner composition includes co-emulsifying a bio-based resin with an insoluble component, such as a pigment or wax, whereby the resin encapsulates the insoluble component. The resulting latex, including the insoluble component encapsulated in the resin, may then be utilized to form a toner. The insoluble component may thus be included in toner particles, which might otherwise be difficult to achieve, using emulsion aggregation processes.

Abstract: An enzymatic polymerization method of covalently linking a colorant to a polyester to produce a colorant-polyester compound, the method including the steps of: (a) providing a reaction solution comprised of an ester monomer, especially a lactone, a colorant having or functionalized to have a hydroxyl group, and an enzymatic catalyst; (b) reacting the ester monomer and the colorant using the enzymatic catalyst to produce a polymeric product, wherein the polymeric product includes a colorant-polyester compound; and (c) separating the polymeric product from the reaction solution. A colorant-polyester compound includes a colorant covalently linked to a polyester. The ester monomer can be a cyclic lactone such as ambrettolide of exaltolide.

Abstract: A toner of a sulfonated polyester resin and at least one colorant is made to contain from about 0.01% by weight to about 3% by weight of dry toner in total of lithium, sodium, zinc and calcium. The sulfonated polyester resin may be an alkali metal sulfonated polyester resin, wherein the alkali metal may be sodium and/or lithium. The toner may be formed in an emulsion aggregation process in which an alkali (II) metal salt such as a zinc salt and/or a calcium salt is used as an aggregating agent.

Abstract: A method of making particles suitable for use as toners includes forming a mixture of sulfonated polyester resin, a colorant dispersion and optionally a wax dispersion, homogenizing the mixture, adding a coagulant to the mixture to aggregate the mixture to form aggregated particles, and coalescing the aggregated particles to form coalesced particles. In the method, when a predetermined average particle size is achieved during th e aggregation and/or coalescing step, a complexing agent that complexes with ions of the coagulant is added in an amount effective to substantially halt any further particle growth. Th e complexing agent is believed to halt further growth by complexing with free coagulant ions still in the solution.
