This invention relates to organic salt compositions useful in the preparation of organoclay compositions, polymer-organoclay composite compositions, and methods for the preparation of polymer nanocomposites. In one embodiment, the present invention provides a pyridinium salt having structure XV wherein Ar6, Ar7, and Ar8 are independently C2-C50 aromatic radicals; “b” is a number from 0 to 2; “d” is a number from 0 to 4; R3 and R4 are independently at each occurrence a halogen atom, a C1-C20 aliphatic radical, a C5-C20 cycloaliphatic radical, or a C2-C20 aromatic radical; Z is a bond, a divalent C1-C20 aliphatic radical, a divalent C5-C20 cycloaliphatic radical, a divalent C2-C20 aromatic radical, an oxygen linking group, a sulfur linking group, a SO2 linking group, or a Se linking group; Ar9 is a C10-C200 aromatic radical, or a polymer chain comprising at least one aromatic group; and X? is a charge balancing counterion.
