    摘要: Provided is a wholly aromatic liquid crystalline polyester resin having excellent heat resistance and formability. The wholly aromatic liquid crystalline polyester resin comprises structural units represented by the following formulae (I) to (V) as essential structural units, wherein the composition ratio (mol %) of the structural units (I) to (V) in the wholly aromatic liquid crystalline polyester satisfies the following conditions: 50 mol %≤structural unit (I)≤75 mol %; 6 mol %≤structural unit (II)≤20 mol %; 1 mol %≤structural unit (III)≤21.5 mol %; 0.5 mol %≤structural unit (IV)≤10.5 mol %; 2.5 mol %≤structural unit (V)≤22 mol %; structural unit (III)>structural unit (IV).

    摘要: The present invention discloses a curable composition comprising: an epoxy compound represented by the following Formula (1); and one selected from the group consisting of: a thermal cationic polymerization initiator, an acid anhydride-based curing agent and a curing accelerator, and a photo-cationic polymerization initiator as well as the cured product therefrom. The above described curable composition is useful in that it allows for the production of a cured product having a high heat resistance. (In the Formula (1), A represents CR17R18; B represents CR19R20; R1 to R20 each independently represents a substituent selected from the group consisting of a hydrogen atom, an alkyl group and an alkoxy group; and n represents 0 or 1, with the proviso that when n is 0, m represents 1, and when n is 1, m represents 0.)
