  • Specific phosphonated copolymers and inorganic particles grafted by said copolymers
    Patent number: 9548508
    Abstract: The invention relates to copolymers comprising a chain of siloxane repeat units of at least two different types, a first type of siloxane repeat unit comprising at least one —OH group on the silicon atom of the siloxane repeat unit and a second type of repeat unit comprising at least one pendant chain on the silicon atom of said repeat unit, this pendant chain consisting of a polymer chain comprising a chain of repeat units carrying at least one group of formula —PO3R1R2 wherein R1 and R2 independently represent a hydrogen atom, an alkyl group or a cation.
