  • Patent number: 7691920
    Abstract: An ink jet ink includes an ink vehicle, wherein the ink vehicle includes at least one wax monomer functionalized to include in the chain at least one reactive group curable upon exposure to radiation. The reactive group is preferably curable via cationic or free radical polymerization. In a preferred embodiment, the ink vehicle includes a wax monomer having a structure: wherein C represents a cationically curable group and R represents a radically curable group. The inks may be used to form an image by jetting the ink onto a transfuse member surface, increasing the viscosity of the ink upon the transfuse member surface, subsequently transferring the ink from the transfuse member surface to an image receiving substrate, and exposing the ink to radiation following the transfer to the image receiving substrate to effect reaction of the at least one reactive group.

  • Patent number: 7482393
    Abstract: A method for producing submicron polytetrafluoroethylene (“PTFE”) powder in a free-flowing, readily dispersible form. The irradiated PTFE starting material is placed in a desired solvent and undergoes grinding until the PTFE particles reach submicron size. The submicron particles are subsequently recovered from the solvent and dried to form a powder that may have particles less than 1.00 ?m in size. The dry PTFE powder may then be readily dispersed to submicron size into a desired application system. The submicron PTFE powder of this method is free-flowing, readily dispersible in various application systems, tends not to “dust” or self-agglomerate. Improved aqueous and organic dispersions of submicron PTFE particles may also be formed that display increased stability and require much less agitation than other processes of forming such dispersions. Such improved PTFE dispersions may be formed with or without the addition of surfactants, wetting agents, rheology modifiers, pH-adjusting agents, and the like.

  • Patent number: 6468595
    Abstract: A thermally-stable cationic photoinitiator capable of flash vaporization under vacuum and temperature conditions of an available flash-evaporation chamber is selected. The photoinitiator is mixed with a cation-polymerizable monomer and/or oligomer of interest and the mixture is flash evaporated and condensed in conventional manner as a film on a cold substrate. The resulting vacuum-deposited, homogeneous layer is cured with a high-energy radiation source that causes the cationic photoinitiator to liberate acidic species that catalyze the crosslinking of the monomer/oligomer compounds in its deposited film form. As a result of the homogeneous, pinhole-free nature of the vacuum deposition process, the thin-film polymer product does not suffer from the disadvantages attendant to prior-art atmospheric processes for cationically-cured polymers.

  • Patent number: 5874042
    Abstract: The present invention aims to improve soundproof and heat insulating properties of a foamed plastic by reducing internal cells pressure inside foamed resins. A base polymer such as a polyester-based polyol and a volatile foaming agent having an conjugate unsaturated group (i. e., conjugate double carbon bonds and/or triple carbon bonds) such as chloroprene (bp. 51.degree. C.) and calcium stearate were blended and then mixed with a hardening agent such as hexamethylene diisocyanate. The volatile foaming agent existing in open cells of the foamed plastic sealed in the Al laminated film and between the film and the foamed plastic, i.e., gap, possesses an unsaturated group, such as isoprene. Thus polymerization may occur by irradiating with electron rays, and the inside of the foams and the gap region may be reduced in pressure while the bag of the laminated film retains its shape.
