| abstract |
The invention relates to at least partially chlorinated copolymers of at least one ethylenically unsaturated phenyl group containing monomer with at least one α, ß-unsaturated monocarboxylic acid and / or at least one α, ß-unsaturated dicarboxylic acid Obtainable by esterification of at least one water soluble polyether, at least one water soluble polyether and an aliphatic dicarboxylic acid, and a carboxylic acid containing at least three carboxyl groups and at least one water soluble polyether. It relates to a low-VOC mixture of star polymers and also to the use of a low-VOC mixture according to the invention for the production of low-VOC pigment pastes or low-VOC paint systems. |
