Abstract (en)
[origin: WO2008002867A2] 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 pyridinium cation having structure (Formula XXV), wherein Ar<SUP>6</SUP>, Ar<SUP>7,</SUP> and Ar<SUP>8</SUP> are independently C<SUB>2</SUB>-C<SUB>50</SUB> aromatic radicals; "b" is a number from 0 to 2; R<SUP>3</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 Ar<SUP>11</SUP> is a C<SUB>2</SUB>- C<SUB>200</SUB> aromatic radical, or a polymer chain comprising at least one aromatic group.
