摘要

Directly aminating the surface of a 2-dimensional layered lattice silicate comprising reacting the lattice silicate in particulate form with gaseous NH.sub.3 at temperatures below 100 C. to form bound NH.sub.2 groups at the surface, the resulting modified 2- dimensional layered lattice silicate and a filled resin system employing the thusly modified silicate.
