Abstract (en)
[origin: WO2008002888A2] 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 polymer-organoclay composite composition comprising (a) a polymeric resin; and (b) an organoclay composition comprising alternating inorganic silicate layers and organic layers, said organic layers comprising a quaternary phosphonium cation having structure X wherein Ar<SUP>1</SUP>, Ar<SUP>2</SUP>, and Ar<SUP>3</SUP> are independently C<SUB>2</SUB>-C<SUB>50</SUB> aromatic radicals; Ar<SUP>4</SUP> is a bond or a C<SUB>2</SUB>-C<SUB>50</SUB> aromatic radical; "a" is a number from 1 to about 200; "c" is a number from 0 to 3; R<SUP>1</SUP> is independently at each occurrence a halogen atom, a C<SUB>1</SUB>-C<SUB>20</SUB> aliphatic radical, a C<SUB>5</SUB>-C<SUB>20</SUB> cycloaliphatic radical, or a C<SUB>2</SUB>-C<SUB>20</SUB> aromatic radical; and R<SUP>2</SUP> is a halogen atom, a C<SUB>1</SUB>-C<SUB>20</SUB> aliphatic radical, a C<SUB>5</SUB>-C<SUB>20</SUB> cycloaliphatic radical, a C<SUB>2</SUB>-C<SUB>50</SUB> aromatic radical, or a polymer chain.
