PROBLEM TO BE SOLVED: To provide a novel polyoxazolidone resin having improved heat resistance.SOLUTION: A polyoxazolidone resin has a structural unit represented by formula (1-1) or (1-2), where Rand Rare each independently a halogen atom, a cyano group, a nitro group, a hydrocarbon group, or a monovalent group having at least one kind selected from -O-, -COO- and -OCO- in a carbon-carbon bond of a hydrocarbon group, m and n are each independently an integer of 0 to 4, and Ris a bivalent or trivalent hydrocarbon group, a bivalent or trivalent group having at least one kind selected from -O-, -COO- and -OCO- in a carbon-carbon bond of a hydrocarbon group, or a bivalent or trivalent group having triazine skeleton. |
