Process for preparing a modified clay, clay, modified, and nanocompu00f3sito polymer clay

摘要

Process to prepare a modified clay, clay, and clay nanocompu00f3sito modified polymer. Processes for the chemical modification of the surface of a clay are exposed.In one form, is provided with a process for modifying the surface chemistry of clay, in which the process comprises: providing a dispersion of clay.It comprises at least a non modified clay in the clay has a first cation that can be exchanged; the addition of a second cation to the dispersion of the clay.At least a portion of the second cation is replaced with at least a portion of the first cation.To form a dispersion of modified clay; and combining at least one agent containing a polar environment with the dispersion of the clay modified, so as to provide a modified clay.
