Nickel stabilizers for synthetic polymers

摘要

Nickel complexes containing ortho- or para-hydroxybenzoate anions and a non-ionic amine ligand are valuable light-stabilizers for polymers, particularly for polyolefins. The complexes may also contain a second carboxylate anion, different from the benzoate anion, and in this case also the amine-free nickel compounds show a high stabilizing action.
