Polymer mixtures containing at least two different comb polymers |
| abstract |
The present invention relates to a process for the preparation of a polymer mixture comprising at least two different comb polymers, wherein the comb polymers each have a polymer backbone comprising side chains linked by ester and/or amide groups, the process comprising The following steps: a) providing and/or preparing a reaction mixture comprising at least a first base polymer bearing acid groups and a second base polymer bearing acid groups, wherein the two base polymers are chemically different; b) jointly esterifying and/or amidating two base polymers with at least one hydroxy-terminated side-chain compound on one side and/or with at least one amino-terminated side-chain compound on one side, resulting in at least two different Comb polymers. |
