    Abstract: A heterocyclic phosphorus mono-, di- or polyester has the constitution of the product prepared by reacting an intermediate of specified type with a di- or polyol or derivative thereof capable of yielding the di- or polyol on hydrolysis, said intermediate of specified type being a heterocyclic phosphorus compound having the constitution of the compound prepared by reacting an olefin polymer or copolymer having at least 50 carbon atoms and containing olefinic unsaturation with a phosphorus trihalide in the presence of a Friedel-Crafts catalyst, preferably consisting of an aluminium halide, to form a reaction product having halogen atoms attached to phosphorus, and thereafter reacting the reaction product with a hydroxy compound, preferably water or methanol, to remove one or both of the halogen atoms attached to the phosphorus atom. Lubricating compositions containing the mono-, di- or polyesters of the invention are also described.

    Abstract translation: 杂环磷单 - ，二 - 或聚酯具有通过使特定类型的中间体与能够在水解时产生二元或多元醇的二元或多元醇或其衍生物反应而制备的产物的构成，所述指定类型的中间体为 在具有优选由卤化铝组成的Friedel-Crafts催化剂存在下，使具有至少50个碳原子并含有烯属不饱和基团的烯烃聚合物或共聚物与三卤化磷反应制备的化合物的组成的杂环磷化合物， 形成具有与磷连接的卤素原子的反应产物，然后使反应产物与羟基化合物，优选水或甲醇反应，以除去与磷原子连接的一个或两个卤素原子。 还描述了含有本发明的单 - ，二 - 或聚酯的润滑组合物。

    Abstract: Novel phenols obtained by reacting a compound of the formula I

    in which ONE X is a hydroxyl group and the other X is selected from hydrogen atoms and tertiary butyl radicals, EACH OF R1 and R2 is independently selected from hydrogen atoms and tertiary butyl radicals, A is selected from phenyl radicals and phenyl radicals substituted by up to 2 tertiary butyl radicals, with the proviso that at least one of R1 and R2 must be a tertiary butyl radical and with the further proviso that at most 3 tertiary butyl radicals may be present per molecule, with phosphorus trichloride and chlorine atoms which may be left on the phosphorus atom are then reacted with water, alcohols, polyalcohols, or phenols, are described and their use as stabilizers against certain deterioration phenomena, especially adverse effect of light, heat or oxidation with organic materials, especially plastics such as polypropylene.
