Abstract of the Disclosure A process for producing a novel cross-linked resin which comprises: reacting a bis(2-oxazoline) compound with a reactive compound which has at least one active hydrogen in the molecule, the reactive compound being at least one selected from the group consisting of a sulfonamide, an acid imide, an aromatic hydroxy-carboxylic acid and a bisphenol sulfone compound, in a molar ratio of the reactive compound to the bis(2-oxazoline) compound of not more than about 2, at an elevated temperature. About 5 to about 95 mole % of the reactive compound is repalceable by a dicarboxylic acid. The cross-linked resin may be usable for the produc- tion of machinery parts such as rolls and gears and embedded moldings of electrical machinery and apparatus parts as well as for electric insulating materials and dental uses. The cross-linked resin may further find applications in, for example, adhesives and various coating compositions.
