    Abstract: The present invention relates to a process for preparing a phosphorus-containing polymer, comprising the steps of (i) copolymerizing at least (a) monoethylenically unsaturated dicarboxylic anhydrides having from 4 to 6 carbon atoms with (b) olefins of the formula CH2═C(R1)R2 where R1 is H or CH3 and R2 is H, CH3, C2H5 or phenyl; (ii) reacting the polymer formed in step (i) with at least one primary or secondary phosphorus-containing amine or a phosphorus-containing alcohol and (iii) at least partly ring-opening the remaining anhydride groups. The invention further relates to phosphorus-containing polymers obtainable from this process, and to processes for preventing Ba/Sr scale with the aid of the polymer.

    Abstract: The present invention relates to a substantially chromium-free process for passivating metallic surfaces of Zn, Zn alloys, Al or Al alloys by treating the surface with an acidic aqueous formulation which comprises at least one substantially noncrosslinked, water-soluble polymer or copolymer containing at least 50% by weight of (meth)acrylic acid units and comprises water or an aqueous solvent mixture comprising at least 50% by weight of water, and by further treating the surface with at least one water-soluble crosslinker comprising at least 2 crosslinking groups selected from the group consisting of azirane, oxirane, and thiirane groups. The invention further relates to passivating layers obtainable by means of the process and to a formulation suitable for this process.
