Disclosed are articles useful as the body of a container for containing gas under pressure, and containers which comprise the articles to which are affixed valves to control the flow of gas out of the container, wherein the articles comprise a hollow container body, having an external surface and having an opening through which gas can enter or leave the interior of the hollow container body; optionally but preferably a layer of fiber-reinforced polymer around the exterior of the container body, and an external layer of elastomer around and sealed to the external surface of the layer of fiber-reinforced polymer if present or else to the cylinder body.

A drag reducing composition comprising at least one non-polyalphaolefin polymer having an average particle size in the range of from about 5 to about 800 micrometers. The non-polyalphaolefin polymer can initially be formed via emulsion polymerization. The initial polymer particles can then be at least partially consolidated and then reduced in size and suspended in a carrier fluid. The resulting drag reducing composition can be added to a hydrocarbon-containing fluid to decrease the pressure drop associated with the turbulent flow of the hydrocarbon-containing fluid through a conduit.

A fiber-reinforced resin molding material is obtained by impregnating a chopped fiber bundle with a matrix resin, has a layered structure including three or more layers in a thickness direction thereof, and satisfies the relationships Lao>Lam and Wao>Wam, where Lao and Wao represent the number average fiber length and the number average fiber bundle width, respectively, of the chopped fiber bundle in the outermost layer thereof, and Lam and Wam represent the number average fiber length and the number average fiber bundle width, respectively, of the chopped fiber bundle in a middle layer thereof.

Porous polymeric resins, reaction mixtures and methods that can be used to prepare the porous polymeric resins, and uses of the porous polymeric resin are described. More specifically, the polymeric resins typically have a hierarchical porous structure plus reactive groups that can be used to interact with or react with a variety of different target compounds. The reactive groups can be selected from an acidic group or a salt thereof, an amino group or salt thereof, a hydroxyl group, an azlactone group, a glycidyl group, or a combination thereof.

A composite film 10 according to the present invention is provided with: a resin film 1 which is formed of a cured product of a photocurable adhesive composition; and solid particles 3 which are affixed, in the form of a single layer, to the resin film 1, while having edges thereof exposed from one and the other main surfaces of the resin film 1. The resin film 1 is formed by irradiating an adhesive layer 1a in a semi-cured state with light 13, said adhesive layer 1a being formed of the adhesive composition.

A transfer sheet has a structure in which a polyester layer as a backing layer, a polyvinyl alcohol (PVA) layer, and a transfer layer, are stacked in this order, where the polyvinyl alcohol layer contains a diol compound and/or triol compound whose adjacent hydroxyl groups are positioned at δ or farther positions with respect to each other, and which satisfies the condition in (i): (i) a T-peel strength at a peel rate of 100 mm/min between the polyester layer and the polyvinyl alcohol layer before a transfer layer is formed but after a humidity has been adjusted in an environment of 23° C., 50% RH, is 30 mN/20 mm or greater. The transfer sheet is intended to offer a single-sheet solution for achieving both normal temperature transfer and thermal transfer when transferring a material having high adhesion to polyester or other material constituting the backing.

The preparation method for the diester structure monomer includes the following steps: dissolving glycolate in a reaction solvent to prepare a glycolate solution; mixing the glycolate solution with triethylamine in a protective atmosphere, and cooling to form a mixture; and keeping the protective atmosphere unchanged, and adding the methacryloyl chloride to the mixture for esterification to generate a diester structure monomer. The diester structure monomer generated by the preparation method for the diester structure monomer has a long diester side chain and a group with a small volume and high acid sensitivity. As a result, a resin synthesized from the diester structure monomer has good adhesive force and film-forming property, high deprotection efficiency and plasticity, and the hardness and brittleness of the resin are improved. Moreover, the prepared diester acid protected structure monomer has the advantages of high yield, low by-product content and easy separation and purification.

A curable composition contains a betaine monomer having a predetermined structure and a polyfunctional (meth)acrylamide compound having a predetermined structure.

A method of forming a void, channel and/or vascular network in a polymeric matrix comprises providing a pre-vascularized structure that includes a matrix material and a sacrificial material embedded in the matrix material in a predetermined pattern, where the matrix material comprises a monomer and the sacrificial material comprises a polymer. A region of the matrix material is activated to initiate an exothermic polymerization reaction and generate a self-propagating polymerization front. As the polymerization front propagates through the matrix material and polymerizes the monomer, heat from the exothermic reaction simultaneously degrades the sacrificial material into a gas-phase and/or liquid-phase byproduct. Thus, one or more voids or channels having the predetermined pattern are rapidly formed in the matrix material.
