Abstract (en)
[origin: WO2008002868A2] 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 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; "d" is a number from 0 to 4; R<SUP>3</SUP> and R<SUP>4</SUP> are 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; Z is a bond, a divalent C<SUB>1</SUB>-C<SUB>20</SUB> aliphatic radical, a divalent C<SUB>5</SUB>-C<SUB>20</SUB> cycloaliphatic radical, a divalent C<SUB>2</SUB>-C<SUB>20</SUB> aromatic radical, an oxygen linking group, a sulfur linking group, a SO<SUB>2</SUB> linking group, or a Se linking group; Ar<SUP>9 </SUP>is a C<SUB>10</SUB>- C<SUB>200</SUB> aromatic radical, or a polymer chain comprising at least one aromatic group; and X<SUP>-</SUP> is a charge balancing counterion.
