  • Transition metal complexes with trivalent phosphorus compounds
    Patent number: 4012399
    Abstract: Ultraviolet light absorbers and stabilizers, particularly for monolefin polymers, are provided from metal complexes of trivalent phosphorus compounds of the formulaeMe (L).sub.n (A).sub.m (L').sub.owhere Me is preferably nickel but can be manganese, iron, copper, molybdenum or tungsten, L is P(X)(Y)(Z) where any one or all of X, Y and Z can be O hydrocarbyl, ##STR1## where R.sub.31 and R.sub.32 are hydrocarbyl or hydrogen, S hydrocarbyl, hydrocarbyl, 2 or 3 of X, Y and Z can form one or more heterocyclic rings with P, A is an anion such as halogen, e.g. Cl, Br, I or F, NO.sub.3, C104, R.sub.33 COO- where R.sub.33 is hydrocarbyl, any hydrocarbyl group can have 1 or 2 halogen substituents, m is 0 or a small whole number, e.g. 1,2,3,4, L' is CO, NO, CN, halogen, o is zero or a small whole number, e.g. 1,2,3,4, n is 1 or another small whole number, e.g. 2,3,4, o+m+n is not greater than the highest coordination number of the metal.
    Type: Grant
