Triazine containing epoxy resins having improved thermal stability

摘要

The thermal stability of epoxy resins prepared by dehydrohalogenating the reaction product of an epihalohydrin with an adduct prepared from a cyanuric halide and a polyhydric aromatic compound is improved by employing as the polyhydric aromatic compound one which is substituted with a hydrocarbyl group, a halogen atom or a nitro group at each ortho position relative to each aromatic hydroxyl group. These epoxy resins are useful in coating and molding compositions and in the preparation of laminates and composites.
