Title: MODIFIED POLYARYLATE RESIN
Abstract:
The present invention provides a polyarylate resin which has excellent curing reactivity and is capable of forming a cured product that has sufficiently excellent heat resistance. The present invention relates to a modified polyarylate resin which contains an unsaturated group and/or an epoxy group at some or all ends of a polyarylate resin, and wherein: the polyarylate resin contains a divalent phenol component and an aromatic dicarboxylic acid component; the divalent phenol component contains an alicyclic divalent phenol represented by general formula (1); and the concentration of the unsaturated group and/or the epoxy group is 100 eq/ton or more. (In formula (1), each of R1, R2, R3 and R4 represents a hydrogen atom, a hydrocarbon group having 1-12 carbon atoms, or a halogen atom; each of R5 and R6 represents a hydrogen atom or a hydrocarbon group having 1-4 carbon atoms; m represents an integer of 4-12; and X represents a carbon atoms that constitutes a saturated aliphatic hydrocarbon ring.)
