Abstract

One-component, heat-curing reactive compositions based on liquid rubbers containing reactive olefinic double bonds and optionally solid rubbers and vulcanization systems based on sulfur have high maxima of the acoustic loss factor over a broad in-use temperature range of around +10° C. to +40° C. in their vulcanized state. These compositions optionally contain fine-particle thermoplastic polymers as an additional component. The compositions are suitable for use as acoustically damping adhesives, sealing compounds or coating compositions.
