Abstract
Polymers bearing the following structural elements per molecule: (A) an average of at least two alkoxylated (poly)alkylenimine units, said alkylene being selected from C2-C10-alkylene and said alkoxylation being selected from ethoxylation, propoxylation, butoxylation and combinations of at least two of the foregoing, (B) at least one polysiloxane unit, and (C) at least one linkage connecting at least two different alkoxylated (poly)alkylenimine units (A) bearing at least one polysiloxane unit (B), each link-age (C) being selected from organic spacers bearing in the range of from 4 to 30 carbon atoms.
