Polymer mixtures containing at least two different comb polymers |
| abstract |
The present invention relates to a process for preparing a polymer mixture containing at least two different comb polymers, wherein the comb polymers each have a polymer backbone having side chains attached via ester and/or amide groups, which process comprises the steps of: a) providing and/or preparing a reaction mixture containing at least a first base polymer bearing acid groups and a second base polymer bearing acid groups, wherein the two base polymers differ chemically; b) conjointly esterifying and/or amidating the two base polymers with at least one unilaterally hydroxyl-terminated side chain compound and/or with at least one unilaterally amino-terminated side chain compound to obtain at least two different comb polymers. The invention further relates to a polymer mixture obtainable with the process of the invention, to a mineral binder composition and to a shaped article obtainable therefrom. Further aspects relate to uses of the polymer mixture in mineral binder compositions. |
