Patent number: 4623480Abstract: Stabilizer systems containing at least two Ni-containing light-stabilizers in which nickel (which, in class 2, optionally contains an additional ligand) forms a complex compound with a compound selected from the group consisting of the classes:(1) 2-hydroxy-4-alkoxybenzophenones(2) 2,2'-thiobis[4-alkylphenols](3) 3,5-dialkyl-4-hydroxybenzoic acid monoalkyl esters(4) 3,5-dialkyl-4-hydroxybenzylphosphonic acid monoalkyl esters(5) 1-phenyl-3-methyl-4-acyl-5-hydroxypyrazole,in which the radicals generally contained are appropriately substituted. After being incorporated into the corresponding polyolefins, these stabilizer systems have a synergistic effect which prevents or at least greatly retards decomposition initiated by light and/or oxygen.Type: GrantFiled: December 31, 1984Date of Patent: November 18, 1986Assignee: Ciba-Geigy CorporationInventor: Francois Gugumus
