Abstract
The invention relates to a compound comprising at least one polymeric chain incorporating phosphorus atoms and consisting, in all or in part, of identical or different repeated units, each of said units being represented by the following formula:wherein X3 represents —[Si(O2)]—; or —O—[Si(R1R2)O]— with R1 and R2 being, independently of each other, a C1-C30 alkyl or alkoxy group, a C5-C30 aryl group; or a mono- or polyorganosilicate derived radical; or —N(R3)— with R3 being —H, a C1-C30 alkyl group or a C5-C30 aryl group, optionally substituted with —OH or —NH2, or at least one unit of general formula (I), and ═X4 represents an electron pair, ═O, ═S, ═NR4 with R4 representing a C1-C30 alkyl group or a C5-C30 aryl group, ═Se or ═Te, and its use for complexing metal atoms.
