Abstract
The chemical reactivity of isocyanuric acid, 2, 4-diamino-6-vinyl-s-triazine (VT) or the intermolecular compound of isocyanuric acid and VT with epoxide resin and the physical properties of their simultaneously cured compounds were described. Isocyanuric acid reacted with epoxide in the presence of imidazole and formed an 2-oxazolidinone ring in the cured compounds. The reactivity of amino groups of VT is considerably higher than 2, 4-diamino-6-ethyl-s-triazine or melamine. The intermolecular compound of isocyanuric acid and VT reacted with epoxide and formed 2-oxazolidinone rings in addition to polymerized epoxide resins and VTs. Simultaneously cured compounds of above s-triazine compounds are better as materials of electric insulation or adhesion than the epoxide resin cured with imidazole.
