Abstract
Abstract Phosphoric esters of polyfluorinated alcohols are disclosed comprising at least one isomer of phosphorous esters of polyfluorinated alcohols, or one of the derivatives thereof, said esters and derivatives thereof corresponding to the general formula: <IMAGE> (I) said two isomers corresponding to formulae (II) and (III): <IMAGE>(II) <IMAGE>(III) wherein Cn F2n+1 is a perfluorinated aliphatic chain, n is an integer from 2 to 18, X and Y are the same or different and are each a halogen atom, a hydroxy radical, the group OM in which M is a metallic equivalent, or an alkoxy, chloroalkoxy, hydroxypolyalkylenoxy, aryloxy, or -NZZ' group in which Z and Z' are the same or different and are each a hydrogen atom or an alkyl, cycloalkyl or aryl group.
