OBJECT

An object is to provide a resin composition capable of forming a crosslinked product that is excellent in hot water resistance and excellent in interlayer adhesiveness when formed into a multilayered structure.

SOLUTION

The resin composition contains an ethylene-vinyl alcohol copolymer (A) and a crosslinking agent (B) with the crosslinking agent (B) in an amount of 0.6 to 15 parts by mass relative to 100 parts by mass of the ethylene-vinyl alcohol copolymer (A), the crosslinking agent (B) being a powder obtained by impregnating a porous body (BS) with a crosslinkable compound (BL) having three or more polymerizable groups and a melting point of no greater than 40° C.

A method for producing a resin additive composition is a method for handling, as a solid, a compound that can maintain a liquid state or fluid state at 100° C. for 30 minutes or longer, and includes causing 100 parts by mass of a styrene-based elastomer (A) to be mixed with 50 to 250 parts by mass of a compound (B) that can maintain a liquid state or fluid state at 100° C. for 30 minutes or longer. A resin additive composition is obtained by mixing 100 parts by mass of a styrene-based elastomer (A) with 50 to 250 parts by mass of a compound (B) having a melting point of 100° C. or lower.

Treated, mesoporous aggregates comprising a plurality of coated particles that comprise an inorganic oxide core having a surface area of about 50 to about 500 square meters per gram and a shell or coating consisting of an array of fluoroalkyl molecular chains covalently bonded to the core at a density of at least one chain per square nanometer. The aggregates are formed by the chemical attachment of fluoroalkyl-alkylsilanes after exposure to an alkylamine and followed by an extraction to remove any unbound organic material. The dense packing of molecular chains in the fluoroalkyl shell combined with a mesoporous structure imparts a very low surface energy, a very high specific surface area, and surface texture over a wide range of length scales. Such features are highly desirable for the creation of, for example, superhydrophobic and superoleophobic surfaces, separation media, and release films.
