A composition comprising:
- a fluorine-containing polymer, the fluorine-containing polymer being a perfluoroelastomer having a cyano group at a terminal of a main chain and/or in a side chain;
- at least one carboxylic acid compound selected from the group consisting of a dicarboxylic acid compound represented by formula (A) and a monocarboxylic acid compound represented by formula (B), and
- at least one cross-linking compounding agent selected from the group consisting of a primary amine compound, a secondary amine compound, an inorganic nitride, an organic tin compound, a peroxide cross-linking agent, a polyol cross-linking agent, a polyamine cross-linking agent, an oxazole cross-linking agent, an imidazole cross-linking agent, and a thiazole cross-linking agent,
- wherein a content of the carboxylic acid compound is 0.05 to 3.0 parts by mass with respect to 100 parts by mass of the fluorine-containing polymer:
- MA1OOC—(YA1)m—COOMA2 Formula (A):
- wherein YA1 represents a single bond, a substituted or unsubstituted alkylene group having 1 to 3 carbon atoms, or a substituted or unsubstituted alkylene group having 2 or more carbon atoms and having an oxygen atom or cyclic structure between carbon-carbon atoms, a substituted or unsubstituted unsaturated aliphatic group, or a substituted or unsubstituted cycloalkylene group having 3 to 10 carbon atoms, MA1 and MA2 are the same or different and represent a cation or an alkyl group, and m is 1;
- when YA1 is a single bond, MA1 and MA2 are the same or different and are a hydrogen ion or an ammonium ion;
- and
- CXB1XB2═CXB3—(CH2)n—COOMB1 Formula (B):
- wherein XB1, XB2, and XB3 are the same or different and are H or a substituted or unsubstituted alkyl group, each MB1 is a hydrogen ion, and n is an integer of 0 to 5.
A composition comprising:
- a fluorine-containing polymer, the fluorine-containing polymer being a fluorine-containing elastomer having a cyano group at a terminal of a main chain and/or in a side chain;
- a carboxylic acid compound that produces carbon dioxide at 40 to 200° C.;
- and
- at least one cross-linking compounding agent selected from the group consisting of a primary amine compound, a secondary amine compound, an inorganic nitride, an organic tin compound, a peroxide cross-linking agent, a polyol cross-linking agent, a polyamine cross-linking agent, an oxazole cross-linking agent, an imidazole cross-linking agent, and a thiazole cross-linking agent.
A moldable composition comprising:
- a fluorine-containing polymer having an iodine atom or a bromine atom, the fluorine-containing polymer being a perfluoroelastomer;
- at least one carboxylic acid compound selected from the group consisting of a dicarboxylic acid compound represented by formula (A) and a monocarboxylic acid compound represented by formula (B);
- and
- a cross-linking compounding agent,
- wherein the moldable composition only contains, as the cross-linking compounding agent, at least one cross-linking compounding agent selected from the group consisting of a primary amine compound, a secondary amine compound, a tertiary amine compound, an inorganic nitride, an organic tin compound, a peroxide cross-linking agent, a polyamine cross-linking agent, an oxazole cross-linking agent, an imidazole cross-linking agent, and a thiazole cross-linking agent, and
- a content of the carboxylic acid compound is 0.05 to 3.0 parts by mass with respect to 100 parts by mass of the fluorine-containing polymer:
- MA1OOC—(YA1)m—COOMA2 Formula (A):
- wherein YA1 represents a single bond, a substituted or unsubstituted alkylene group having 1 to 3 carbon atoms, or a substituted or unsubstituted alkylene group having 2 or more carbon atoms and having an oxygen atom or cyclic structure between carbon-carbon atoms, a substituted or unsubstituted unsaturated aliphatic group, or a substituted or unsubstituted cycloalkylene group having 3 to 10 carbon atoms, MA1 and MA2 are the same or different and represent a cation or an alkyl group, and m is 1;
- when YA1 is a single bond, MA1 and MA2 are the same or different and are a hydrogen ion or an ammonium ion;
