摘要
An aqueous polishing agent, comprising, as the abrasive, at least one kind of polymer particles (A) finely dispersed in the aqueous phase and having at their surface a plurality of at least one kind of functional groups (a1) capable of interacting with the metals and/or the metal oxides on top of the surfaces to be polished and forming complexes with the said metals and metal cations, the said polymer particles (A) being preparable by the emulsion or suspension polymerization of at least one monomer containing at least one radically polymerizable double bond in the presence of at least one oligomer or polymer containing a plurality of functional groups (a1); graft copolymers preparable by the emulsion or suspension polymerization of at least one monomer containing at least one radically polymerizable double bond in the presence of at least one oligomeric or polymeric aminotriazine-polyamine condensate; and a process for the chemical and mechanical polishing of patterned and unstructured metal surfaces making use of the said aqueous polishing agent.
