    摘要： An epoxy resin composition which is useful for encapsulating materials which are sensitive to shock, extreme temperature or chemical attack in which an epoxy resin is cured by the use of a curing agent comprised of an anhydride which is partially reacted to the corresponding half ester by reaction with a polyol under catalysis with a uranyl salt. The anhydride, anhydride half ester uranyl salt mixture forms a storable curing agent capable of promoting the complete cure of epoxy resin compositions in short time periods at temperatures of 170*F or less.

    摘要： THIS PATENT DESCRIBES A NOVEL STORABLE EPOXY-IMIDE RESIN PRECURSOR COMPRISING A CURABLE OXIRANE MONOMER AND AN IMIDE, THE IMPROVEMENT WHEREIN THE SYSTEM IS PROVIDED WITH AN ACTIVATED CHROMIUM III TRICARBOXYLATE SALT CATALYST WHICH CONTAINS AVAILABLE COORDIATION SITES, AND WHICH SITES ARE RENDERED UNAVAILABLE IN THE PRESENCE OF CERTAIN NON-REACTIVE, REMOVABLE ELECTRON DONATING SOLVENTS. THAT IS TO SAY, THE CATALYST COMPOUND, IN THE PRESENCE OF PARTICULAR SOLVENTS IS RENDERED NONCATALYTIC; ON THE REMOVAL OF SAID SOLVENTS, CATALYTIC ACTIVITY IS RESTORED. THESE SOLVENTS INCLUDE BUT ARE NOT LIMITED TO SUCH POLAR ELECTRON COORDINATING SOLVENTS AS REMOVABLE METHANOL, ETHANOL, N,N-DIMETHYL FORMAMIDE, DIOXANE, TETRAHYDROFURAN, DIMETHYL SULFOXIDE, DIMETHYL SULFOLANE, NITRO ALKANES, NITRO AROMATICS, TETRAMETHYL UREA, N,N-DIMETHYLACETAMIDE, N-METHYLCAPROLACTAM AND N-METHYL PYRROLIDONE. UPON THE REMOVAL OF ONLY THE SOLVENT AS BE EVAPORATION, THE ACTIVITY OF THE CATALYST IS RESTORED, BY THE FORMATION OF UNOCCUPIED COORDINATION SITES, WHEREBY THE REACTION OF THE OXIRANE COMPOUND WITH THE IMIDE CAN TAKE PLACE.

    摘要： Disclosed are organic, UV resistant epoxy resins derived largely from vegetable oil based materials. More specifically, the present invention provides a virtually non-toxic, hypoallergenic UV resistant resin and method of producing and using the same that gives off substantially no VOCs and no disagreeable odors. The composition comprises a vegetable oil-based polyfunctional carboxylic acid, a cycloaliphatic anhydride, and an epoxy compound either of bicyclic difunctional epoxy resin, epoxidized vegetable oil or epoxidized polymer chains. The composition further comprises a catalyst and a wetting agent. In its cured state the material is leather like and exhibits high tensile strength as well as unusually high, totally reversible elongation. In an alternative embodiment, the resin comprises a cyclic anhydride (Lindride 16E). With increased amounts of cyclic anhydride, increased heat distortion temperature is exhibited; all while maintaining a high reversible elongation and high tensile strength In an additional alternative, an increased amount of Chromium III Octoate is used and in another alternative Phosphoric Acid.

    摘要： A polymerizable epoxy compound composition containing an anionic polymerization initiator which can be easily produced, can attain a high polymerization rate and a high degree of polymerization, and can realize an epoxy polymer having properties unobtainable so far, an improvement in cured polymer properties, etc.; and a method of polymerizing an epoxy compound. The composition is an anionically polymerizable composition comprising a monofunctional epoxy compound or a di- or more functional epoxy resin and a polymerization initiator, the polymerization initiator comprising the potassium or sodium salt of a monocarboxylic acid monomer. The method, which is for producing a polymer of epoxy compounds, comprises polymerizing a monofunctional epoxy compound or a di- or more functional epoxy resin by anionic polymerization with the aid of the potassium or sodium salt of a monocarboxylic acid monomer.
