New 7-amino-1,3,5-triaza-adamantane derivs. are of formula (I): In the formula if n=1, R is 1-17C (iso)alkyl, phenyl-1-4C-alkyl, a phenyl or naphthyl, opt. with 1 or 2 Cl, a OH or 1-3 1-4C alkoxy or alkyl substits., or a 5- or 6-membered N- or O-heterocycle. If n=2, R is 2-6C alkylene or phenylene. (I) are used as stabilisers for organic polymers, esp. polyolefins and halogenated polymers, at 0.01-5 wt.pts., w.r.t. the polymers, opt. in conjunction with costabilisers. In an example, 7-pentylidene-amino-1,3,5-triazaadamantane was prepd. from 7-amino-1,3,5-triazaadamantane and valeraldehyde. |
