(a) 25 bis 99 Gew.-% organisches Phosphit oder Phosphonit, (b) 0,01 bis 50 Gew.-% organisches Amin und (c) 0,01 bis 25 Gew.-% säurebindendes Metallsalz enthalten, njeweils bezogen auf das Gesamtgewicht der Zusammensetzung, nsowie ein Verfahren zur Stabilisierung organischer Phosphite oder Phosphonite gegen Hydrolyse durch Zusatz von organischem Amin und säurebindendem Metallsalz.Compositions are described which (a) 25 to 99% by weight of organic phosphite or phosphonite, (b) 0.01 to 50% by weight of organic amine and (c) contain 0.01 to 25% by weight of acid-binding metal salt, each based on the total weight of the composition, and a method for stabilizing organic phosphites or phosphonites against hydrolysis by adding organic amine and acid-binding metal salt.n n n The compositions described are notable for their excellent resistance to hydrolysis and have good storage stability even at high atmospheric humidity. The compositions and process products according to the invention can advantageously be used as stabilizers for organic material against the damaging influence of heat, oxygen and / or light. |
