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&#x2014;O(&#x2014;CH(CH)&#x2014;CHO&#x2014;)(CH&#x2014;CHO&#x2014;)&#x2014;]P(&#x2550;O)(OH)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.

Alkoxylated phosphate esters for lubricant compositions

An additive for a bitumen or polymer modified bitumen product, which is prepared by mixing together a sulphur-based product, a vulcanized rubber, for example, a waste vulcanized rubber, preferably a fatty acid, and a bitumen, is described. The use of this additive for preparing, with very limited gaseous emissions, elastomer-containing bituminous product is also described. Such use may be especially suitable for making bituminous coated material including, for example, asphalt concrete.
