The present invention relates to particulate concentrate compositions formed by intercalation of a polymer polymerizing component into the galleries of a layered inorganic cation exchange composition initially in proton exchanged form and to the use of the particulate concentrates for the preparation of cured polymer-inorganic nanolayer hybrid composite compositions. The polymer polymerizing component comprising the particulate concentrate contains a basic group for reaction with the protons of the inorganic cation exchanger. Also, the polymer polymerizing component contains a functional group for polymerization reaction with a polymer precursor, a mixture of polymer precursors, or a polymer melt which is introduced into the galleries of the inorganic cation exchanger and reacts with the polymer polymerizing component to form a cured polymer-inorganic nanolayer hybrid composite. In the most preferred embodiment of the invention the layered inorganic composition is selected from the family of 2:1 layered silicate cation exchangers.

[ We claim:] [1.] A particulate composition used to prepare a cured polymer and layered inorganic composition composite which comprises:a polymer polymerizing component which has been intercalated into the particles of a layered inorganic composition with nanolayers and with galleries between the nanolayers wherein:(1) the layered inorganic composition has at least 10% of cation exchange sites occupied by protons as H.sup.+ prior to being intercalated a remainder being occupied by inorganic ions other than the protons; and(2) the polymer polymerizing component contains at least one basic group for reaction with the protons of the layered inorganic composition, wherein in use of the particulate composition the nanolayers are separated by a polymer precursor or polymer melt which is introduced into the galleries of the inorganic layered composition and reacts with the polymer polymerizing component and wherein the weight ratio of the polymer polymerizing component to layered inorganic composition is between about 1:100 and 100:1.
