  • Patent number: 10441940
    Abstract: Complexing or chelating agents that offer strong, selective bonding with uranium as well as a broad pH range of effectiveness, specifically including the pH range around 8.2, together with the acrylic double bonds required for radiation-induced grafting on polymers to remove uranium from a solution such as seawater. The novel adsorbing species are phosphorus-containing molecules, in particular organic phosphates, phosphonates and phosphoric acids. Organic phosphorus compounds, for example, organic phosphates, phosphonates, and phosphoric acids, are attached to polymer fibers to form fibers, fiber fabrics or membranes that are effective, or show activity, in uranium adsorption.

    Abstract: Highly reliable interconnections for microelectronic packaging. In one embodiment, dielectric layers in a build-up interconnect have a gradation in glass transition temperature; and the later applied dielectric layers are laminated at temperatures lower than the glass transition temperatures of the earlier applied dielectric layers. In one embodiment, the glass transition temperatures of earlier applied dielectric films in a build-up interconnect are increased through a thermosetting process to exceed the temperature for laminating the later applied dielectric films. In one embodiment, a polyimide material is formed with embedded catalysts to promote cross-linking after a film of the polyimide material is laminated (e.g., through photo-chemical or thermal degradation of the encapsulant of the catalysts).

In various embodiments, the polymers are formed by the reaction of a multifunctional alcohol or ether and a difunctional or higher order acid to form a pre-polymer, which is cross-linked to form the elastic biodegradable polymer. In preferred embodiments, the cross-linking is performed by functionalization of one or more OR groups on the pre-polymer backbone with vinyl, followed by photopolymerization to form the elastic biodegradable polymer composition or material. Preferably, acrylate is used to add one or more vinyls to the backbone of the pre-polymer to form an acrylated pre-polymer. In various embodiments, acrylated pre-polymers are co-polymerized with one or more acrylated co-polymers.

    Abstract: The present invention discloses new types of poly(amidoamine) (PAMAM) dendrimer-cross-linked polyimide membranes and methods for making and using these membranes. The membranes are prepared by cross-linking of asymmetric aromatic polyimide membranes using a PAMAM dendrimer as the cross-linking agent. The PAMAM-cross-linked polyimide membranes showed significantly improved selectivities for CO2/CH4 compared to a comparable uncrosslinked polyimide membrane. For example, PAMAM 0.0 dendrimer-cross-linked asymmetric flat sheet poly(3,3?,4,4?-diphenylsulfone tetracarboxylic dianhydride-3,3?,5,5?-tetramethyl-4,4?-methylene dianiline) (DSDA-TMMDA) polyimide membrane showed CO2 permeance of 135.2 A.U. and CO2/CH4 selectivity of 20.3. However, the un-cross-linked DSDA-TMMDA asymmetric flat sheet membrane showed much lower CO2/CH4 selectivity (16.5) and higher CO2 permeance (230.8 GPU).

  • Patent number: 8367772
    Abstract: A crosslinked aramid polymer comprising a first aramid backbone which is crosslinked through a poly(meth)acrylic acid with a second aramid backbone. The crosslinked aramid polymer is obtained by polymerizing a monomeric aromatic diamine with a monomeric aromatic diacid, or halide or ester thereof in the presence of poly(meth)acrylic acid, followed by a curing step. The crosslinked aramid polymer is crosslinked through its amide bonds and can be made to a fiber, film or fibrid.
