LIQUID POLYHYDRIC HYDROXY RESIN, METHOD FOR PRODUCING THE SAME, CURING AGENT FOR EPOXY RESIN, EPOXY RESIN COMPOSITION, CURED PRODUCT OF THE SAME, AND EPOXY RESIN

摘要

PROBLEM TO BE SOLVED: To provide a polyhydric hydroxy resin which shows a liquid state with low viscosity even if an allyl group is not introduced, and can obtain a cured product with low viscosity when used as a curing agent for epoxy resin.SOLUTION: There is provided a liquid polyhydric hydroxy resin which has a constitutional unit represented by formula (u1) and a constitutional unit represented by formula (u2), and has a total content of the constitutional unit represented by formula (u2) and a compound represented by formula (m2) of 70-90 mass% with respect to the whole liquid polyhydric hydroxy resin, and a mass average molecular weight of 800-1,600. In formulae, Ris a hydrogen atom or a methyl group; Ris a linear or branched hydrocarbon group having 10-25 carbon atoms; X is a hydrogen atom or a hydroxyl group; m and n are each independently 0 or 1; and Y is a hydrogen atom or a methyl group.SELECTED DRAWING: None
