Zusammenfassung: | A curable composition comprising (A) a vinylidene fluoride type elastomer which is a copolymer of vinylidene fluoride (a1), at least one perfluoroolefin (a2) selected from the group consisting of tetrafluoroethylene, hexafluoropropylene and perfluoro(alkyl vinyl ether) and a cyano group-containing monomer (a3) (the proportion of vinylidene fluoride exceeds 20% by mole), and (B) a compound generating ammonia at 40° to 330° C. alone as a curing agent. The present invention can provide a curable composition of a vinylidene fluoride type elastomer assuring improved crosslinking speed and making it possible to use a cheap curing agent, and a molded article obtained from the curable composition. Physical properties under normal conditions can also be improved by the presence of the solvent having affinity for the compound generating ammonia. |
