Rheology control agent

Water-Based Muds. About 85% of all drilling fluids are water-based systems. The types depend on the composition of the water phase (pH, ionic content, etc), viscosity builders (clays or polymers), and rheological control agents (deflocculants or dispersants (qv)). [Pg.174]

Overall, the key element in many of these approaches is the complex needs of the ink to meet the needs of the deposition technique, to facilitate the formation of the desired material with appropriate properties and to facilitate the desired thickness, roughness, line resolution, and uniformity. This set of constraints will in most cases require an appropriate combination of precursors, solvents, surfactants, adhesion promoters, and rheology control agents (e.g., see Chapter 12 for more discussion).29 For new metal organic and nanoparticle precursors, the fabrication of inks is still an emerging science.

Our research interest in this field is based on the perception that these dendritic polymers could be useful as polymer-rheology control agents as well as spherical, multifunctional macromonomers. Hyperbranched polymers, which were not only thermally and chemically robust under the conditions used, but also could be economically obtained, were created to evaluate these concepts. The latter requirement led us to pursue the one-step polymerization of AB -type monomers. We will review mostly the synthesis of aromatic polymers with stable chemical linkages prepared by the single-step direct method, and we will briefly compare them with polymers made by more controlled multistep syntheses.
