Abstract:
1. A flame-retardant thermoplastic polyhydroxy polyether resin, wherein the flame-retardant thermoplastic polyhydroxy polyether resin is obtained by reacting at least one epoxy resin (A) selected from glycidyl esters of divalent aliphatic carboxylic acids having 15 to 64 carbon atoms or glycidyl ethers of divalent aliphatic alcohols having 15 to 64 carbon atoms with a phosphorus atom-containing divalent phenol compound (B) at a phenol group equivalent of 0.9 to 1.1 with respect to an epoxy group equivalent of 1, wherein the amount of the component (A) is 2 to 52 mol % with respect to the whole resin, the weight average molecular weight thereof is 10,000 to 200,000, and the phosphorus content thereof is 1 to 5 wt %, and elongation thereof is 15% to 120%.
