ABSTRACT:
A novel thermosetting resin can be obtained by mixing 1 equivalent or more of a polyfunctional isocyanate per 1 equivalent of a polyfunctional epoxide and then carrying out a polymerization reaction of the mixture in the presence of the catalyst which forms isocyanurate rings and oxazolidone rings so as to enable the mixture to form 2 or more isocyanurate rings directly connected with oxazolidone rings through an isocyanate residues.
The resulting thermosetting resin has excellent electrical, chemical and impact resistances and excellent self-extinguishing properties. Said resin is used as an electric insulating material.
