  • Process for preparation of high molecular weight epoxy resin
    Patent number: 6107419
    Abstract: Present invention relates to a process for preparing a high molecular weight epoxy resin which has a weight average molecular weight value more than 40,000 and an epoxy equivalent weight less than 10,000 g/eq. This high molecular weight epoxy is prepared by a reaction of a divalent epoxy resin with a bisphenol compound in the presence of a catalyst and a solvent characterized in utilizing 1.10 to 1.03/1 of molar ratio of epoxy group/phenolic hydroxyl group.
