A process for the stabilization of polyolefins against oxidation, characterized in that 0.05 to 5% by weight, based on the polyolefin, of a mixture of two components a and b in the ratio is added to the polyolefins as a stabilizer. 1: 5 to 2: 1, being a compound of the general formula 1 ** (See formula) ** or of general formula 2 ** (See formula) ** where R represents hydrogen or an aliphatic hydrocarbon radical with 1 to 18 carbon atoms or halogen and n is a number from 1 to 8 or can be zero and X represents an alkoxy group with 1 to 18 carbon atoms or an amino group, whose atoms of hydrogen may also be fully or partially substituted, and R 'in formula 2 representing a straight or branched chain hydrocarbon radical having up to 18 carbon atoms, which may optionally still contain one or more free OH groups, and m being an integer from 2 to 6, and b consisting of an organic phosphite of the general formula ** (See formula) ** wherein R1, R2 and R3 represent aliphatic radicals independently of one another having 8 to 18 carbon atoms, aromatic radicals, arylalkoxy radicals or alkylaryl radicals, optionally in admixture with other stabilizers customary for polyolefins.
