Abstract
Homostructured, cation exchanged, layered compositions containing mixed onium and alkali metal, alkaline earth metal, protonated hydronium ions and mixtures thereof are described. Particulate concentrates formed by intercalation of a polymer component into the galleries of the layered inorganic and organic homostructured layered cation exchange composition and to the use of the particulate concentrates for the preparation of cured polymer-inorganic nanolayer hybrid composite compositions are described. In the most preferred embodiment of the invention the layered inorganic composition is selected from the family of 2:1 layered silicate clays.
