Reaction products of amine monomers and polymers containing saturated heterocyclic moieties as additives for electroplating baths
Reaction products of amines and polymers containing saturated heterocyclic moieties may be used as levelers in metal electroplating baths. The reaction products may plate metal with good surface properties and good physical reliability.
1. A reaction product of one or more amine monomers and one or more polymers, the one or more polymers have the formula:
where R 1 and R 2 can be the same or different and comprise hydrogen, linear or branched (C 1 -C 5 )alkyl, hydroxyl, linear or branched (C 1 -C 5 )hydroxyalkyl, linear or branched (C 1 -C 5 )carboxyalkyl, linear or branched (C 1 -C 5 )alkoxy, linear or branched (C 1 -C 5 )haloalkyl, aryl, linear or branched arylalkyl, or linear or branched, aminoalkyl and m is an integer of 2-8.
2. The reaction product of claim 1 , wherein the one or more amine monomers are chosen from compounds having formula:
where R 29 is hydrogen or linear or branched (C 1 -C 5 )alkyl, r is an integer of 0 to 8 with the proviso that when r is 0, R′ is joined to the nitrogen atom by a covalent bond and R′ is a linear or branched nitrogen containing moiety, aromatic or non-aromatic heterocyclic groups.
