| titleOfInvention | Epoxy resin production method and high molecular weight epoxy resin |
| abstract | <P>PROBLEM TO BE SOLVED: To provide a method for producing an epoxy resin having flexibility and heat resistance and being very useful in a variety of applications such as molding materials, casting materials, laminating materials, coating materials, adhesives, or resists. <P>SOLUTION: The method for producing a powdery epoxy resin comprises step (1) of reacting a compound having a phenolic hydroxy group with epichlorohydrin in the presence of an alkali metal hydroxide to prepare an epoxy resin, step (2) of adding a good solvent for the epoxy resin to the obtained residue (epoxy resin) to dissolve the epoxy resin, and step (3) of mixing the obtained solution with a poor solvent for the epoxy resin to precipitate the powdery epoxy resin. <P>COPYRIGHT: (C)2006,JPO&NCIPI |
