Abstract

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 an organoclay composition comprising alternating inorganic silicate layers and organic layers, said organic layers comprising a quaternary phosphonium cation having structure Xwherein Ar1, Ar2, and Ar3 are independently C2-C50 aromatic radicals; Ar4 is a bond or a C2-C50 aromatic radical; “a” is a number from 1 to about 200; “c” is a number from 0 to 3; R1 is independently at each occurrence a halogen atom, a C1-C20 aliphatic radical, a C5-C20 cycloaliphatic radical, or a C2-C20 aromatic radical; and R2 is a halogen atom, a C1-C20 aliphatic radical, a C5-C20 cycloaliphatic radical, a C2-C50 aromatic radical, or a polymer chain.
