The invention relates to polyfunctional polymers suitable in particular for the treatment of metal surfaces (metal finishing) and comprising: monomer units u1 bearing phosphonic acid functions; monomer units u2 bearing amine functions; and optionally monomer units u3 bearing alcohol units &#x2014;OH.

Polyfunctional polymers based on phosphonate units and amine units

A polymer includes (a) one or more first monomeric units, each independently comprising at least one bicycloheptyl-polyether, bicycloheptenyl-polyether or branched (C-C)alkyl-polyether group per monomeric unit, wherein the bicycloheptyl-polyether or bicycloheptenyl-polyether group may optionally be substituted on one or more ring carbon atoms by one or two (C-C)alkyl groups per carbon atom, and (b) one or more second monomeric units, each independently comprising at least one pendant linear or branched (C-C)alkyl-polyether group per monomeric unit, provided that the first and second monomeric units cannot both comprise a branched (C-C)alkyl-polyether group and is useful as a component in liquid compositions, such as aqueous latex coating compositions, personal care compositions, home care compositions, and institutional or industrial care compositions.
