<p>A polyfluoroalkyl silicone having the general formula:
M<Sub>a</Sub>M'<Sub>b</Sub>D<Sub>c</Sub>D'<Sub>d</Sub>T<Sub>e</Sub>T'<Sub>f</Sub>Q<Sub>g</Sub>;
where
M = R<Sup>1</Sup><Sub>u</Sub>R<Sup>2</Sup><Sub>v</Sub>R<Sup>3</Sup><Sub>w</Sub>SiO<Sub>1/2</Sub> with the sum of the subscripts u + v + w being 3 and the subscripts v and w are each independently 0 or 1;
M' = R<Sup>4</Sup>R<Sup>5</Sup>R<Sup>6</Sup>SiO<Sub>1/2</Sub>;
D = R<Sup>7</Sup><Sub>x</Sub>R<Sup>8</Sup><Sub>y</Sub>SiO<Sub>2/2</Sub> with the sum of the subscripts x + y being 2 and y is 0 or 1;
D' = R<Sup>9</Sup>R<Sup>10</Sup>SiO<Sub>2/2</Sub> ;
T = R<Sup>11</Sup><Sub>z</Sub>SiO<Sub>3/2</Sub> with the subscript z being 1;
T' = R<Sup>12</Sup>SiO<Sub>3/2</Sub>; and
Q = SiO<Sub>4/2</Sub>;
where the substituent groups R<Sup>2</Sup>, R<Sup>3</Sup>, R<Sup>4</Sup>, R<Sup>5</Sup>, R<Sup>6</Sup>, R<Sup>8</Sup>, R<Sup>9</Sup>, R<Sup>10</Sup>, and R<Sup>12</Sup> are each independently selected from the group of one to forty carbon atom monovalent hydrocarbon radicals, the subscripts a, b, c, d, e, f, and g are zero or positive integers with the substituent groups, R<Sup>1</Sup>, R<Sup>7</Sup>, and R<Sup>11</Sup>, each independently selected from the group of consisting of monovalent polyfluoroalkyl groups having the formula CF<Sub>3</Sub>(CF<Sub>2</Sub>)<Sub>n</Sub>(CH<Sub>2</Sub>)<Sub>m</Sub> and monovalent polyfluoroalkyl groups having the formula CF<Sub>3</Sub>(CF<Sub>2</Sub>)<Sub>n</Sub>J(CH<Sub>2</Sub>)<Sub>m</Sub> where the subscript n is an integer that ranges from about 3 to about 20, the subscript m is an integer that ranges from about 2 to about 20, J is a divalent methylene group (CH<Sub>2</Sub>), divalent sulfur (S), or oxygen (O); subject to the following limitations on the stoichiometric subscripts a, b, c, and e:
<UnorderedLists id="ula01" listStyle="none" compact="compact"><ListItem>1) a + b ≥ 2;</ListItem><ListItem>2) a + c + e ≥ 1; and</ListItem></UnorderedLists> a(u) + c(x) + e(z) ≥ 2 as a carrier fluid for electro-active materials thereby providing for an electro-viscous fluid.</p> |
