| 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 and prepolymers which are condensible 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. |
