A curable polyphenylene ether (PPE) resin composition comprising (a) PPE and (b) a compound having a 3,4-dihydro-3-substituted-1,3-benzoxazine backbone or a mixture thereof with a ring-opening polymer. Cured PPE composition obtained by hardening the said PPE composition; And a laminated structure using the curable PPE composition or the cured PPE resin composition. Since the curable PPE composition of the present invention exhibits excellent chemical resistance, moisture resistance, dielectric properties, heat resistance, flame retardancy, and dimensional stability after curing, dielectric materials, insulation materials, heat resistances in the fields of electric / electronics industry, aerospace / aircraft industry, etc. It can be used advantageously as a material. In particular, it can be advantageously used as a resin composition for forming an insulating layer such as a curable single-sided printed board, a double-sided printed board, a multilayer printed board, a flexible printed board, a semi-rigid board, and a substrate having excellent heat dissipation characteristics. |
