Abstract: The present application can provide a phthalonitrile compound and a use thereof. The phthalonitrile compound has a novel structure, and can exhibit an excellent effect in a use to which the phthalonitrile compound can be applied. An example of the use of the phthalonitrile compound may be a raw material or precursor for, so-called, a phthalonitrile resin, a phthalocyanine dye, a fluorescent whitening agent, a photographic sensitizer, an acid anhydride, or the like.

Abstract: The present application relates to a polymerizable composition, a prepolymer, a phthalonitrile resin, a composite, a process for preparing the same, and a use thereof. The present application can provide a polymerizable composition comprising a curing agent which has excellent heat resistance and does not cause defects such as voids that may adversely affect physical properties. In addition, the present application allows for the polymerizable composition to exhibit appropriate curing properties, processing temperatures and process windows and to be capable of forming a composite of excellent physical properties. The present application can provide a resin having both advantages of a phthalonitrile resin and a polyimide by curing a phthalonitrile compound as a raw material monomer with a curing agent having a polyimide structure.

Abstract: The present application relates to a phthalonitrile resin and the like. The present application can provide a phthalonitrile resin, and a polymerizable composition and prepolymer using the same, which can exhibit excellent curability, a suitable processing temperature and a wide process window, and form a composite having excellent physical properties. Also, according to the present invention, there may be provided a phthalonitrile resin, and a polymerizable composition and prepolymer using the same, which can exhibit appropriate viscosity characteristics and thus provide a final product without deterioration of mechanical physical properties or the like due to bubbles generated during processing.

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.

Abstract: The present application relates to a novel phthalonitrile compound and a use thereof. The phthalonitrile compound has a novel structure and can exhibit excellent effects in a use known for which a phthalonitrile compound can be applied. The use of the phthalonitrile compound can be exemplified by a material or a precursor such as a phthalonitrile resin, a phthalonitrile dye, a fluorescent whitening agent, a photographic sensitizer, or an acid anhydride.
