The present disclosure is directed to triblock copolymer based anion exchange membranes (AEMs) and methods for making same. The membranes are useful as separators in electrochemical devices, such as fuel cells, electrolyzers, water desalination systems, and redox flow batteries.

One object of the present invention is to provide a polyolefin resin foam which does not have a difference between the front side and the back side on the top and bottom surfaces which sandwich in the thickness direction the foam which is excellent in flexibility, buffer property, and heat insulation property despite its thinness, and which can be used suitably in the fields of architecture, electricity, electronics, vehicles, and the like as a variety of heat-resistant sealing materials. The surface hardness of the foam measured by a micro rubber hardness tester is 30° or more and 70° or less, and the centerline average roughness Ra75 of a first surface portion on one side of the foam in the thickness direction and of a second surface portion on the other side of the foam in the thickness direction is 5 μm or more and 20 μm or less.

In a conventional self-healing material, although the resin properties after self-healing are restored to the same level as the initial refractoriness and strength of the resin, no further extension of life can be expected. A resin cured product according to the present invention includes: a first vinyl monomer having an ester bond; a second vinyl monomer having a hydroxyl group; a transesterification reaction catalyst; and a boron compound.

Provided is a resin for foam molding excellent in foam molding property and low-temperature impact resistance. According to the present invention, provided is a resin for foam molding including a component A, a component B and a component C. The component A is a long-chain branched homopolypropylene, the component B is a long-chain branched block polypropylene, the component C is a polyethylene-based elastomer, and when a total of the components A to C is 100 parts by mass, content of the component A is 20 to 70 parts by mass, content of the component B is 20 to 70 parts by mass, and content of the component C is 1 to 20 parts by mass.

An ion exchange membrane material is composed of a crosslinked polymer network including a first poly(styrene-b-ethylene-r-butylene-b-styrene) triblock copolymer (SEBS), and second SEBS, and a linker crosslinking the first SEBS and the second SEBS. At least one phenyl group from the first SEBS and the second SEBS is functionalized with an alkyl group, and the carbon at the benzylic position of these alkyl groups is saturated with at least two additional alkyl groups. The linker is a diamine bound to the alkyl functional groups. The ion exchange membrane material is made via a substantially simultaneous quaternization and crosslinking reaction between the diamine linker and SEBS functionalized with alkyl halide groups. Increasing concentration of crosslinker in produces membranes with reduced water uptake, leading to an expectation of enhanced stability under hydrated conditions and greater durability. Advantageously, this reduction in water uptake came with little change to ion exchange capacity.

Provided is a resin which is excellent in terms of solubility in common solvents, crosslinking temperature, time required for crosslinking, solvent resistance (cracking resistance), breakdown voltage, leakage current, solvent wettability, and planarity in cases where the resin is formed into a thin film. A resin which comprises repeating units represented by formula (1) and formula (2), and wherein the repeating unit represented by formula (2) is contained in an amount of 20% by mole or more relative to the total amount of the repeating units represented by formula (1) and formula (2).
