摘要： A water-soluble thermoplastic composition for three-dimensional modeling comprising poly(2-ethyl-2-oxazoline) is disclosed. The composition in the form of an extrudable object may be extruded by an extrusion apparatus in a programmed pattern onto a base as a ribbon of liquified polymer to create a support structure for a prototype object or to create a water-soluble polymeric element.

摘要： A carrier is comprised of a thermoplastic polymer such as polyetheretherketone which is formed or fabricated as a uniform thickness, double sided flat sheet of material with wafer passages therethrough and gear teeth formed or fabricated around the peripheral edge thereof so as to be cooperative with a wafer polishing machine. An extrusion or rolling or calendering process provides a flat carrier which is, optionally, coated with thermoset polymer or thermoplastic film.

摘要： A manufacturing method comprising the steps of forming at first solidified wax layer of a desired shape, depositing onto the first solidified wax layer at least one layer of a liquid resin formulation, solidifying the layer of liquid resin formulation, depositing a second wax layer on to the combination of the first solidified wax layer and the layer of solidified resin formulation, solidifying the second wax layer, and separating the solidified resin formulation from first and second wax layers. Preferably, the resin formulation comprises at least one monofunctional water soluble vinyl or acrylic monomer in combination with a low molecular weight aliphatic polymer having acrylic or methacrylic acid functionality. The solidified wax and resin formulation layers can be machined as may be desired to form mold of a given shape comprising wax layers when the layer of formulation is separated from the wax layers.

摘要： A dispersant system for formulating stable non-aqueous siliceous particulate slurries, comprising a vehicle comprising a liquid ester, and a dispersant comprising an alkoxylated aminoalcohol and organophosphate ester. Siliceous particulate slurries in accordance with the present invention can include slurries containing siliceous ceramic particulate (i.e., silicon nitride, silicon carbide, silica, and silicon metal powders partially oxidized by air exposure). A wide variety of linear and cyclic organic esters can be used as a vehicle component, including lactones. The alkoxylated aininoalcohol is typically an ethoxylated aminoethanol oligomer. A wide variety of aromatic and nonaromatic organophosphate ester compounds can be used for the second dispersant component.
