Zusammenfassung:Thermoset compositions useful for dampening vibrations at elevated temperatures are disclosed. The thermoset compositions may have a glass transition temperature of 150 DEG C or greater, a tan d peak of 0.2 or greater, and a tan delta peak width measured at half-height larger than about 40 DEG C, each as measured by dynamic mechanical thermal analysis (DMTA) at a frequency of 1 Hz. The thermoset compositions may be used to dampen vibrations at temperatures in excess of 100 DEG C.
