    Abstract: The present invention provides a polymer electrolyte fuel cell sealing material excellent in hot water resistance and acid resistance, in which sealing performance does not decrease even in a case where a polymer electrolyte fuel cell is driven for a long period of time.
    The polymer electrolyte fuel cell sealing material of the present invention contains a carboxyl group-containing acrylonitrile-butadiene copolymer (a) and an epoxy resin (b), in which the component (a) is preferably a carboxyl group-containing acrylonitrile-butadiene copolymer in which a content of acrylonitrile is 5% to 50% by mass and a carboxyl group equivalent calculated from a number-average molecular weight is 100 to 20,000.

    Abstract: [Object] To provide a curable composition for a polymer electrolyte, which enables a polymer electrolyte to strongly adhere to another substrate such as a heat-resistant polymer in a short time, and is excellent in terms of reliability (in particular, no peeling even in immersion in hot water) in its adhesion state, as well as to provide a layered body.
    [Solution] A curable composition for a polymer electrolyte, including: a component (A): a radical polymerizable compound having a (meth)acryloyl group, a component (B): a compound having, in one molecule, an epoxy group and a skeleton of at least one selected from the group consisting of polybutadiene, polyisoprene, hydrogenated polybutadiene, and hydrogenated polyisoprene, and a component (C): a radical polymerization initiator, in which a content of each of the components (A) to (C) based on the entire composition is as follows,
    the component (A): from 30 to 98.9% by mass
    the component (B): from 1 to 40% by mass, and
    the component (C): from 0.1 to 15% by mass.

    Abstract: The present invention aims to provide a curable resin composition from which a cured product having high tensile strength and high extensibility can be obtained. A resin composition comprises the following ingredients (A) to (C): ingredient (A): a polymer which has one or more (meth)acryloyl groups and has a polyisobutylene skeleton containing a -[CH 2 C(CH 3 ) 2 ]- unit; ingredient (B): a radical polymerization initiator; and ingredient (C): a monomer (c1) which has an alicyclic structure containing a (meth)acryloyl group and a substituent of a hydrocarbon group having 2 to 20 carbon atoms or a monomer (c2) which has a (meth)acryloyl group and a dicyclopentenyl group or adamantyl group.
