  • Patent number: 9219182
    Abstract: The fluoropolymer compositions of the present invention generally incorporate ingredients comprising one or more fluoropolymers, an ultraviolet light protection component (hereinafter UV protection component), and optionally one or more additional ingredients if desired. The UV protection component includes a combination of at least one hindered tertiary amine (HTA) compound having a certain structure and a weight average molecular weight of at least 1000. This tertiary amine is used in combination with at least one organic, UV light absorbing compound (UVLA compound) having a weight average molecular weight greater than 500. When the HTA compound and the UVLA compound are selected according to principles of the present invention, the UV protection component provides fluoropolymer compositions with significantly improved weatherability characteristics for protecting underlying materials, features, structures, components, and/or the like.

  • Patent number: 9101906
    Abstract: The present invention provides porous body precursors and shaped porous bodies. Also included are catalysts and other end-use products based upon the shaped porous bodies and thus the porous body precursors. Finally, processes for making these are provided. The porous body precursors comprise a precursor alumina blend capable of enhancing one or more properties of a shaped porous body based thereupon. The need to employ modifiers to achieve a similar result may thus be substantially reduced, or even avoided, and cost savings are thus provided, as well as savings in time and equipment costs.

  • Patent number: 8513154
    Abstract: The present invention provides porous body precursors and shaped porous bodies. Also included are catalysts and other end-use products based upon the shaped porous bodies and thus the porous body precursors. Finally, processes for making these are provided. The porous body precursors, comprise one or more topography-enhancing additives, i.e., additives that are capable of at least marginally enhancing one or more of surface area, aspect ratio, pore volume, median pore diameter, surface morphology, etc. Downstream products need not necessarily comprise the topography-enhancing additives in order to exhibit the benefits of their inclusion in the porous body precursors.

  • Publication number: 20110059843
    Abstract: The present invention provides porous body precursors and shaped porous bodies. Also included are catalysts and other end-use products based upon the shaped porous bodies and thus the porous body precursors. Finally, processes for making these are provided. The porous body precursors incorporate at least a first oxophilic high oxidation state transition metal. Because the oxophilic high oxidation state transition metal is incorporated into the porous body precursors, it is thought that it will become relatively uniformly distributed therethrough, and thus, provide property enhancements to shaped porous bodies and catalysts based thereupon.

  • Publication number: 20100280261
    Abstract: The present invention provides porous body precursors and shaped porous bodies. Also included are catalysts and other end-use products based upon the shaped porous bodies and thus the porous body precursors. Finally, processes for making these are provided. The porous body precursors are germanium doped and comprise a precursor alumina blend. It has now surprisingly been discovered that inclusion of germanium, alone or in combination with such a blend, in porous body precursors can provide control over, or improvements to, surface morphology, physical properties, and/or surface chemistry of shaped porous bodies based thereupon. Surprisingly and advantageously, heat treating the shaped porous bodies can result in additional morphological changes so that additional fine tuning of the shaped porous bodies is possible in subsequent steps.

    Abstract: This invention is a method comprising providing a substrate, forming a first layer on the substrate, wherein the first layer has a dielectric constant of less than 3.0 and comprises an organic polymer, applying an organosilicate resin over the first layer, removing a portion of the organosilicate resin to expose a portion of the first layer, and removing the exposed portions of the first layer. The invention is also an integrated circuit article comprising an active substrate containing transistors and an electrical interconnect structure containing a pattern of metal lines separated, at least partially, by layers or regions of an organic polymeric material having a dielectric constant of less than 3.0 and further comprising a layer of an organosilicate resin above at least one layer of the organic polymer material.

  • Patent number: 5923945
    Abstract: The invention is a process for the preparation of coated nitride powder, comprising contacting one or more metal complex(es), organo-aluminum material, optionally one or more silicon compounds or mixtures thereof, with nitride powder under conditions such that coated nitride powder is formed. A metal complex is a metal-containing system which is soluble in a host liquid. The process of the invention is a process for making coated nitride powder and obtaining the desirable properties of coated nitride powder, while maintaining the desirable properties of the uncoated powder, such as good thermal conductivity, for use in electronic applications. In another aspect, the invention is a coated nitride powder which has the advantageous properties of the uncoated powder and is a desirable alternative to current nitride coatings.

  • Patent number: 5710382
    Abstract: Aluminum nitride powder, aluminum nitride platelets, powdered solid solutions of aluminum nitride and at least one other ceramic material such as silicon carbide, and composites of aluminum nitride and transition metal borides or carbides are prepared by combustion synthesis at low gaseous nitrogen pressures. Porous bodies of aluminum nitride or composites of aluminum nitride and transition metal borides or carbides are also prepared by combustion synthesis at these pressures. The porous bodies are suitable for infiltration, either as formed or after being coated with at least one layer of a silicate material, by polymers or metals. The powders are also suitable for preparing dense sintered bodies. The aluminum nitride powder is also used to prepare AlN sintered bodies.
