US Classification:

524445000, 524121000

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 X wherein Ar, Ar, and Arare independently C-Caromatic radicals; Aris a bond or a C-Caromatic radical; “a” is a number from 1 to about 200; “c” is a number from 0 to 3; Ris independently at each occurrence a halogen atom, a C-Caliphatic radical, a C-Ccycloaliphatic radical, or a C-Caromatic radical; and Ris a halogen atom, a C-Caliphatic radical, a C-Ccycloaliphatic radical, a C-Caromatic radical, or a polymer chain.
