ABSTRACT:
It is now possible to provide reaction resin mixtures based on organic polyisocyanates and organic polyepoxides that can be hot-cured to high-quality plastics having isocyanurate and oxazolidinone groups that are largely storage-stable at room temperature, without their curing having to be stopped at any time, so that the systems exist in an intermediate "B-stage" (i.e., in a state that is solid at ambient or moderately elevated temperature but still fusible), so that at any later time, for example after pulverizing or dissolving in a suitable solvent, they can be converted by shaping and further thermal action to their ultimate, crosslinked and no longer fusible final state.
