Abstract
A method of producing a layered lattice silicate which is surface modified with an organic material wherein said silicate in substantially dry, particulate form is contacted with an organic monomer, co-monomers or a prepolymer, and surface polymerization or reaction in situ on the silicate in the presence of a gaseous hydrogen atmosphere is effected.
