摘要： A photocurable liquid resin which comprises (A) a step of producing a conjugated diene-based polymer or a conjugated diene/aromatic vinyl-based copolymer, which has a weight-average molecular weight of 5,000 to 40,000 and a molecular weight distribution of 3.0 or smaller, by polymerizing a conjugated diene-based monomer or a combination of a conjugated diene-based monomer and an aromatic vinyl-based monomer in a saturated hydrocarbon-based solvent using a dilithium initiator, (B) a step of producing a conjugated diene-based polymer polyol or a conjugated diene/aromatic vinyl-based copolymer polyol by reacting the produced polymer or copolymer with an alkylene oxide, (C) a step of producing a hydrogenated conjugated diene-based polymer polyol or a hydrogenated conjugated diene/aromatic vinyl-based copolymer polyol by hydrogenating the produced polymer polyol or copolymer polyol, and (D) a step of reacting the hydrogenated polymer polyol or copolymer polyol with a compound having a photocurable unsaturated hydrocarbon group. A material comprising the produced resin exhibits excellent barrier property against water vapor, excellent heat resistance and a hardness suitable for a material having rubber elasticity and is advantageously used as sealing a material.
