    Abstract: 7-[N-(2-alkylidenimino-isobutylamino)]-1,3,5-triazaadamantanes and 7-[N-(2-arylidenimino-isobutylamino)]-1,3,5-triazaadamantane are prepared from 7-amino-1,3,5-triazaadamantane by two condensation steps. The new compounds are very good stabilizers against decomposition of polymers by heat and UV-light.
