Abstract

A polymer represented by Formula or structure (I) wherein at least one of each R, R 1 , R 2 , R 3 , R 4 , R 5 , and R 6 is independently hydrogen, alkyl, aryl, arylalkyl, alkoxy, halogen, cyano, or nitro; x, y, a and b represent the number of groups and rings, respectively; and n represents the number of repeating groups or moieties.

Claims (30)

wherein at least one of R 1 and R 2 is not hydrogen;

wherein a, b, x, and y are independently from 0 to about 3; and

wherein n represents a number of from 2 to about 5,000.

2. A polymer in accordance with claim 1 wherein n represents a number of from about 100 to about 1,000, or from about 10 to about 200.

3. A polymer n accordance with claim 1 wherein n represents a number of from about 20 to about 100.

4. A polymer in accordance with claim 1 wherein at least one of R, R 1 , R 2 , R 3 , R 4 , R 5 and R 6 is alkyl.

5. A polymer in accordance with claim 1 wherein at least one of R, R 1 , R 2 , R 3 , R 4 , R 5 and R 6 is aryl.

6. A polymer in accordance with claim 1 wherein at least one of R, R 1 , R 2 , R 3 , R 4 , R 5 and R 6 is nitro or cyano.

7. A polymer in accordance with claim 1 wherein at least one of R, R 1 , R 2 , R 3 , R 4 , R 5 and R 6 is selected from the group consisting of methyl, ethyl, propyl, butyl, pentyl, hexyl, heptyl, octyl, nonyl, decyl, undecyl, dodecyl, tridecyl, tetradecyl, pentadecyl, hexadecyl, heptadecyl, octadecyl, nonadecyl, eicosanyl, phenyl, octylphenyl, dodecylphenyl, octoxyphenyl, and dodecyloxyphenyl.

8. A polymer in accordance with claim 1 wherein at least one of R, R 1 , R 2 , R 3 , R 4 , R 5 and R 6 is arylalkyl.

9. A polymer in accordance with claim 1 wherein alkyl contains from about 1 to about 25 carbon atoms.

10. A polymer in accordance with claim 1 wherein aryl contains from 6 to about 48 carbon atoms.

11. A polymer in accordance with claim 1 wherein aryl contains from 6 to about 18 carbon atoms.
