Abstract:
A modified phenolic hydroxyl-containing resin, which does not contain a vaporizing component at a baking procedure comprising a resin of formula (1) wherein X represents a residue of difunctional phenol and n is 0 or a positive integer; and wherein the X's at different positions may be the same or different; said resin having a phenolic hydroxyl group equivalent of from 300 to 1200 g/eq made from the process of partially epoxidizing 1.2 to 10 moles of difunctional phenol with 1 mole of epihalohydrin to obtain a partially epoxidized epoxy resin; reacting the partially epoxidized epoxy resin with unreacted difunctional phenol, from which unreacted difunctional phenol is removed until there remains less than 0.1% by weight of unreacted difunctional phenol in the modified resin.
