ALKOXYLATED PHOSPHATE ESTERS FOR LUBRICANT COMPOSITIONS

The present invention concerns a composition suitable for working and shaping metals, in particular providing a lubricating effect, including polymers of the following formula: [R-O(-CH(CH3)-CH2O-)n(CH2-CH2O-)p-]1+x P(=O)(OH)2-x in which: R is a linear or branched, preferably linear, saturated or unsaturated hydrocarbon group, comprising between 8 and 12 carbon atoms; n is a number, which may or may not be an integer, between 6 and 20; p is a number, which may or may not be an integer, between 4 and 25; and x is a number between 0 and 1, and in particular between 0.1 and 0.9. 本发明涉及种适合用于加工和成形金属、特别地提供润滑效果的组合物，该组合物包括具有下式的聚合物：[R-O(-CH(CH)-CHO-)(CH-CHO-)-]P(＝O)(OH)，其中：R是包含在8与12之间个碳原子的、直链或支链的优选直链的、饱和或不饱和的烃基；n是在6与20之间的数，其可以是或可以不是整数；p是在4与25之间的数，其可以是或可以不是整数；并且x是在0与1之间、并且特别地在0.1与0.9之间的数。
