Abstract
A reactive composition, rapidly polymerizable already starting from room temperature, comprises a liquid mixture consituted by at least one organic polyisocyanate, at least one compound containing one or more epoxy groups and a liquid catalyst constituted by, or containing, at least one compound falling within the scope of the general formula ##STR1## in which the substituents have the meanings reported in the following; the compound which contains the epoxy group(s) can be constituted by the catalyst only. Such a composition can turn into a polymeric material having softening temperatures as high as 300.degree. C. and even higher.
