摘要:
The present invention relates to a process for the alkoxylation of a first polymer comprising at least one monomer unit having NH groups and optionally NH2 groups, wherein the first polymer has a molecular weight Mw of at least 500 g/mol, comprising the steps of (a) reacting the first polymer with alkylene oxide in a reaction mixture comprising a solvent until the average degree of alkoxylation of each NH group and each optional NH2 group, calculated as two NH groups, is from 0.75 to 1.25; (b) adding a second polymer of formula (I), wherein R is a linear or branched alkyl group having from 1 to 20 carbon atoms, each R′ is independently a linear or branched alkyl group having from 1 to 20 carbon atoms or hydrogen, each n is independently from 1 to 5 and m is from 5 to 40, to the reaction mixture of step (a); (c) at least partially removing the solvent from the reaction mixture of step (b); and (d) further reacting the reaction mixture of step (c) with alkylene oxide at a given temperature until the average degree of alkoxylation of each NH group and each optional NH2 group, calculated as two NH groups, of the first polymer is from 2 to 40. The present invention also relates to a polymer composition obtainable from that process and the use of such a polymer composition.

摘要:
A process for removing a bulk material layer from a substrate and planarizing the exposed surface by CMP by (1) providing an CMP agent exhibiting at the end of the chemical mechanical polishing, without the addition of supplementary materials, the same SER as at its start and a lower MRR than at its start, —an SER which is lower than the initial SER and an MRR which is the same or essentially the same as the initial MRR or a lower SER and a lower MRR than at its start; (2) contacting the surface of the bulk material layer with the CMP agent; (3) the CMP of the bulk material layer with the CMP agent; and (4) continuing the CMP until all material residuals are removed from the exposed surface; and a CMP agent and their use for manufacturing electrical and optical devices.

A composition comprising a source of metal ions and at least one leveling agent obtainable by condensing at least one trialkanolamine of the general formula N(R1—OH)3 (Ia) and/or at least one dialkanolamine of the general formula R2—N(R1—OH)2 (Ib) to give a polyalkanolamine(II), wherein the R1 radicals are each independently selected from a divalent, linear or branched aliphatic hydrocarbon radical having from 2 to 6 carbon atoms, and the R2 radicals are each selected from hydrogen and linear or branched aliphatic, cycloaliphatic and aromatic hydrocarbon radicals having from 1 to 30 carbon atoms, or derivatives obtainable by alkoxylation, substitution or alkoxylation and substitution of said polyalkanolamine(II).
