ABSTRACT:
Advanced epoxy resin products are prepared by reacting a triglycidyl ether of a trihydric phenol such as the triglycidyl ether of 1,1,1-tri(hydroxyphenyl)methane with a dihydric phenol such as bisphenol A. These advanced epoxy resins are non-sintering solid resins useful in the preparation of electrical potting or molding compositions.
