摘要:
A method for treating a substrate is disclosed in which a propellant stream is passed through a channel and directed toward a substrate. Substrate pre-marking or post-marking treatment material is controllably introduced into the propellant stream and imparted with sufficient kinetic energy thereby to be made incident upon a substrate. A multiplicity of channels for directing the propellant and treatment material allow for high throughput, high resolution in-situ treatment. Marking materials and treatment materials may be introduced into the channel and mixed therein prior to being made incident on the substrate, or mixed or superimposed on the substrate without registration. One example is a single-pass, full-color printer.
摘要:
A carrier comprised of a core and thereover a polymer, and which polymer contains dispersed therein a mixture of an inorganic polymer, and an organic metallic polymer.
摘要:
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.
摘要:
A process which comprises maintaining a mixture of carbon dioxide, surface treating agent and colorant at a temperature of from about -10.degree. C. to about 200.degree. C., and optionally removing carbon dioxide.
摘要:
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.
摘要:
A process for the preparation of polymer compositions which comprises mixing a conductive component with an anionic polymeric latex containing a polymer; adding a cationic surfactant, or flocculant whereby the aggregation of the latex particles and the conductive component particles results; subsequently adding colloidal stabilizer, followed by the addition of a base to obtain a pH of from about 7 to about 12; heating above about the polymer glass transition temperature thereby enabling the severage, or breakage of the formed aggregated particles; further heating above about the polymer glass transition temperature enabling the coalescence of the polymer and conductive component particles; and optionally washing and drying the resulting coalesced product.
摘要:
A process for preparing silane metal oxides comprising reacting a metal oxide with an amine compound to form an amine metal oxide intermediate, and subsequently reacting said intermediate with a halosilane.
摘要:
Disclosed is a free radical polymerization process for the preparation of a thermoplastic resin or resins comprising heating a mixture of a free radical initiator, a stable free radical agent, and at least one polymerizable monomer compound to form a thermoplastic resin or resins with a high monomer to polymer conversion; cooling said mixture; optionally isolating the thermoplastic resin or resins; and optionally washing and drying thermoplastic resin or resins.Related free radical processes are also disclosed for the preparation of mixtures and block copolymer thermoplastic resins. Resins prepared by the disclosed processes possesses a narrow polydispersity and a modality that is controlled by the selection of a free radical initiator and stable free radical agent addition step or steps.
