    Abstract: A conductive resin composition which includes an epoxy resin (A), a compound (B) having a (meth)acryloyl group and a glycidyl group, a phenolic resin curing agent (C), a radical polymerization initiator (D) and a conductive particle (E). The conductive resin composition which may be B-staged (semi-cured) at a relatively low temperature to exhibit sufficient tack-free properties and excellent pressure-sensitive tackiness. This permits temporary bonding of parts without involving solvent evaporation or light illumination, thereby reducing or avoiding an increase in facility costs. The conductive resin composition may thereafter be cured (C-staged) to provide a cured product having a desirable bond strength, while maintaining a low specific resistivity.

  • Patent number: 8268251
    Abstract: An early warning sulfur detection system for detecting the presence of corrosive gases, especially elemental sulfur (S8), in air employs a substrate that includes a polymer-bound phosphine compound having sulfur-getting functionality. The phosphine compound in the polymer reacts with any airborne elemental sulfur. This reaction is accompanied by a decrease in the fluorescence intensity (If) of the substrate. The If of the substrate is monitored in real time by a spectrofluorometer to detect a change in fluorescence intensity (?If). In an embodiment sited in a data center, an alarm is triggered if the ?If is above a predetermined threshold, thereby providing a real-time, early warning to IT professionals that corrective action is required to protect metal conductors from corrosion. Preferably, the phosphine compound in the polymer does not react with other components in the air (e.g., carbon dioxide).

  • Patent number: 5350802
    Abstract: Blends of carbonate and monovinylidene aromatic copolymers containing selected low molecular weight halogenated epoxy compounds, in combination with tetrafluoroethylene polymers, are shown to have surprising combinations of impact and ignition resistance and be very suitable for electroplating applications. In general the selected epoxy compounds can be represented by the following formula: ##STR1## where, preferably, R is hydrogen; X is bromine; i is 2; L is 2,2-isopropyl; n is from 0 to 1. Polymer blends based on from about 65 to about 98 weight percent carbonate polymer, from about 2 to about 25 percent by weight monovinylidene aromatic copolymer, preferably rubber modified, and from 0 to about 10 percent by weight of a rubbery core/shell graft copolymer impact modifier are suitable for preparation of these compositions. It has been found desirable to employ from about 1 to about 20 percent by weight low molecular weight halogenated epoxy compound, and from 0.

  • Patent number: 5322896
    Abstract: The invention relates to a process for producing improved water absorbing resin comprising the steps of treating water absorbing resin particles (A) with an aqueous solution of a water-soluble compound (B) and a crosslinking agent (C), reacting, and obtaining resin particles crosslinked in the surface vicinity; and a water absorbing resin obtained by this process possessing the absorption characteristics of an absorbency under a pressure-free state of 50 times or more to physiological saline solution, and an absorbency under the pressurized state of 30 times or more to physiological saline solution. The water-soluble compound (B) is at least one water-soluble compound selected from the group consisting of alkylene-oxide adducts of monofunctional alcohols (1), a monofunctional salts of organic acids (2), and lactams (3), and inert to (A) and (C); and the crosslinking agent (C) has two or more functional groups capable of reacting with (A).

  • Patent number: 5252669
    Abstract: A water reducible resin for use in a coating composition is produced by grafting in organic solvent a thermoplastic polymer onto a thermosetting polymer that has been copolymerized with acid group-containing monomers to render the resultant polymer water soluble. Thermoplastic polymer is also grafted onto a phosphatized polyepoxide for the sake of adhesion of a coating to a substrate. A film formed from a waterborne coating composition containing the grafted polymers as a binder has both the toughness properties characteristic of a thermoplastic and the flexibility properties of a thermosetting resin.
