    • Process for preparing aryl esters of phosphonous acid of formula (V), where A is non-existent or a direct bond or a divalent hydrocarbon bridge with 1 to 6 carbon atoms, which can be substituted by the groups mentioned below, or a heteroatom, cycloalkylidene with 4 to 8 carbon atoms or phenylalkylidene with 7 to 12 carbon atoms, n is equal to 1 or 2, R as a monovalent residue denotes certain non-aromatic or aromatic hydrocarbon residues, the aromatic residues denoting substituents such as alkyl, alkoxy, alkylthio, dialkylamino, aryl, aryloxy or halogen, and as a divalent residue denotes a phenylene or naththylene residue, which can carry non-aromatic hydrocarbon residues as substituents, R is a non-aromatic hydrocarbon residue with 1 to 18 carbon atoms, aryl, arylmethyl, arylethyl or arylisopropyl, each aryl containing 6 to 10 carbon atoms, and R denotes hydrogen or one of the groups mentioned under R . In a first stage a halogenated hydrocarbon R (-Hal)n, in which R has the above-mentioned meaning, n = 1 or 2, and the halogen has an atomic weight of at least 35, is converted under Grignard conditions with at least molar quantities of magnesium to the corresponding organomagnesium compounds R (MgHal)n. These are reacted in a second stage with phosphoric acid-bis-arylester halides of formula (VI), where R , R and Hal have the above-mentioned meanings, to form the phosphonous acid arylester (V). The invention also relates to a plastics moulding material, in particular a polyolefin moulding material, containing the phosphonous acid arylester of formula (V). The properties of the moulding material are superior to those of materials which contain phosphonites produced by prior art techniques.
