| 摘要 |
A method is described in which a layered lattice silicate is surface modified with an organic material by reacting said layered lattice silicate in particulate form with a reactant system comprising gaseous NH3 at temperatures below about 1000 DEG C. and contacting the aminated silicate in particulate form with an organic compound selected from the group of monomers, co-monomers, prepolymers and compounds condensable with the amine group, such as a nylon precursor, in the presence of gaseous hydrogen. The surface modified silicates are useful as fillers in a filled polymer system comprising a matrix polymer and a filler.
