Abstract: Intercalates formed by contacting a layered material, e.g., a phyllosilicate, with an intercalant surface modifier selected from the group consisting of a compound having an alkyl radical containing at least 6 carbon atoms, a compound containing an aromatic ring, and mixtures thereof, said surface modifier including a matrix material-reactive functional group, to sorb or intercalate the intercalant surface modifier between adjacent platelets of the layered material. Sufficient intercalant surface modifier is sorbed between adjacent platelets to expand the adjacent platelets to at least about 10 Å, up to about 100 Å. The intercalated complex can be combined with an organic liquid into a viscous carrier material, for delivery of the carrier material, or for delivery of an active compound; or the intercalated complex can be combined with a matrix polymer to form a strong, filled polymer matrix.

Abstract: A process for the preparation of a modified kaolin from a kaolin group mineral which includes expansion and contraction of layers of the kaolin group mineral. The layers comprising one Si-tetrahedral sheet and one Al-octahedral sheet. The expansion and contraction may be initiated by initial intercalation of a reagent which can penetrate kaolin layers to reach an interlayer region therebetween to form an intercalate. Subsequently, the intercalation nay be followed by de-intercalation which involves the removal of the reagent. By the above process, there is provided crystalline modified kaolins having the following properties: (i) an increased interlayer space compared to corresponding kaolin group minerals; (ii) an increased susceptibility to intercalation by cations, anions or salts compared to corresponding kaolin group minerals; and (iii) an increased exfoliated morphology compared to corresponding kaolin group minerals.
