  • Patent number: 10683261
    Abstract: The present application can provide a phthalonitrile compound and a use thereof. The present application can provide a phthalonitrile compound capable of forming a phthalonitrile resin by self-curing or of serving as a curing agent after being mixed with another phthalonitrile compound, and a use of the phthalonitrile compound. The phthalonitrile compound can form a phthalonitrile resin by rapid self-curing even at a low temperature and does not create any defects resulting from the use of a conventional curing agent. Also, the phthalonitrile compound can be applied as a curing agent after being mixed with another compound, in which case, even if the content of the compound applied as a curing agent increases, the total content of the phthalonitrile resin obtained does not decrease, and thus a resin exhibiting an excellent degree of cure can be provided.
