AGENTS BINDING AND MODIFYING RHEOLOGY

摘要

The invention concerns copolymers containing carboxylic groups having both a binding function and a rheology modifying function or a viscosity depressant function or a crushing aid function of aqueous suspensions of pigments and/or mineral fillers, enabling to obtain grains of pigments and/or mineral fillers, reconstituted and consisting of elementary particles having a BET specific surface area ranging between 0.5 m2/g and 200 m2/g, grains which can be easily re-dispersed in thermoplastic resins. The invention also concerns the sintered mineral materials and their uses.
