| titleOfInvention | Epoxy Resin, Method for Producing Same and Epoxy Resin Composition Thereof |
| abstract | An epoxy resin represented by general formula (I), which satisfies numerical formula (1) mentioned below and comprises hydrolytic halogen of 0.05 wt. % or less, said epoxy resin being produced by the procedure as follows: after dissolving 0.8 to 1.3 mole of epihalohydrin to 1 mole of divalent phenol in a solvent, a pre-reaction is performed over 30 to 70 minutes by adding dropwise 0.25-0.35 mole of 30˜50% aqueous solution of alkali metal hydroxide over 30 to 70 minutes thereto, and thereafter, 0.65-0.75 mole of the remaining 30˜50% aqueous solution of alkali metal hydroxide is added dropwise over about 1 hour to complete the reaction over 1 to 3 hours. n n n n n n n n n n n n wherein n is an integer of 0 or more; n A 1 and A 2 are residue of divalent phenol, and can be same or different; n both R 1 and R 2 are H or n n n n n n n n n n n n n n wherein,n X: epoxy equivalent (g/eq); Y: phenolic hydroxyl group equivalent (g/eq). |
