  • MIXTURE COMPOSITION CONTAINING COPOLYMERS BASED ON UNSATURATED CARBOXYLIC ACID AND ALKENYL ETHER DERIVATIVES AND COPOLYMERS AND TERPOLYMERS CONTAINING SULFO GROUPS AND USE THEREOF
    Publication number: 20110218289
    Abstract: The invention relates to a mixture composition having dispersing properties, containing copolymers based on unsaturated mono or dicarboxylic acid derivatives and oxyalkylene ethers as component I and water-soluble copolymers and terpolymers containing sulfo groups having an average molecular weight of 50 000-20 000 000 g/mol as component II. By combining both components, which can be respectively characterized by four different structural units, it is possible to obtain mixture compositions which can, more particularly, be used as dispersing agents for organic and/or inorganic pigments and fillers, in addition to known applications in the field of structural chemistry. In the field of structural chemistry, the mixture compositions are suitable for use on account of the dispersing properties thereof, particularly in ceramic systems and in water-based painting and coating systems.
