Reversible aminal gel compositions, methods, and use
A well treatment composition for use in a hydrocarbon-bearing reservoir, optionally as a kill pill, and comprising a reversible aminal gel composition. The reversible aminal gel composition includes a liquid precursor composition. The liquid precursor composition is operable to remain in a liquid state at about room temperature. The liquid precursor composition comprises an organic amine composition; an aldehyde composition; a polar aprotic organic solvent; and a metal salt composition. The liquid precursor composition transitions from the liquid state to a gel state responsive to an increase in temperature in the hydrocarbon-bearing reservoir. The gel state is stable in the hydrocarbon-bearing reservoir at a temperature similar to a temperature of the hydrocarbon-bearing reservoir, and the gel state is operable to return to the liquid state responsive to a change in the hydrocarbon-bearing reservoir selected from the group consisting of: a decrease in pH in the hydrocarbon-bearing reservoir and an addition of excess metal salt composition in the hydrocarbon-bearing reservoir.

NOVEL METHODS FOR SOL-GEL POLYMERIZATION IN ABSENCE OF SOLVENT AND CREATION OF TUNABLE CARBON STRUCTURE FROM SAME
The present application is directed to methods for solvent-free preparation of polymers and their subsequent processing into activated carbon materials. These methods unexpectedly demonstrate ability to tune pore structure in the polymer gel and carbon produced there from, while also providing distinct advantages over the current art.
Post spacer, liquid crystal display panel including the same, and method for manufacturing liquid crystal display panel
The present disclosure discloses a post spacer, which is applied to a liquid crystal display panel. The post spacer has a material having a structure as represented by Formula 1, wherein X includes at least one of groups represented by Formulae 2-1 to 2-5; Y includes at least one of groups represented by Formulae 3-1 and 3-2; at least one of the X and the Y has a molecular chain end having a group capable to chemically cross-link with materials of alignment layers; and at least one of the X and the Y has a side chains having a group capable to generate a hydrogen bond or intermolecular force with a material of liquid crystal molecules. The present disclosure also discloses a liquid crystal display panel having the post spacers described above and a method of manufacturing the same.
Film-forming composition for ink-jet coating
A film-forming composition for ink-jet coating which comprises: a triazine-ring-containing polymer including, for example, the repeating unit structure represented by the following formula [3]; and an organic solvent comprising more than 50 mass % solvent based on a glycol dialkyl ether. The composition is less apt to corrode the heads of ink-jet coating devices, and droplets thereof are satisfactorily ejected in ink-jet coating. Therefore, with the composition, it is possible to easily produce a high-refractive-index film according to a desired pattern through pattern printing by an ink-jet coating device. ##STR00001##

CYANATE ESTER DUAL CURE RESINS FOR ADDITIVE MANUFACTURING
A method of forming a three-dimensional object is carried out by: (a) providing a cyanate ester dual cure resin; (b) forming a three-dimensional intermediate from said resin, where said intermediate has the shape of, or a shape to be imparted to, said three-dimensional object, and where said resin is solidified by exposure to light; (c) optionally washing the three-dimensional intermediate, and then (d) heating and/or microwave irradiating said three-dimensional intermediate sufficiently to further cure said resin and form said three-dimensional object. Compositions useful for carrying out the method, and products made from the method, are also described.
