Claims14
A homopolymer having a repeating group, wherein the repeating group is structure (1):
- wherein R′″ is selected from alkyl having from about 1 to about 35 carbon atoms;
- and n is a number of from 2 to about 5,000.
A homopolymer having a repeating group, wherein the repeating group is represented by structure (21):
- wherein n represents the number of repeating units, and is a number of from 2 to about 5,000.
A homopolymer having a repeating group, wherein the repeating group is one of the following structures (9)-(13):
- wherein R′″ and R″″ are different and are selected from alkyl having from about 1 to about 35 carbon atoms;
- X represents F, Cl, Br, CN, or NO2;
- and n is a number of from 2 to about 5,000.
A homopolymer having a repeating group of Formula (I):
- wherein R is alkoxy;
- R′ and R″ are independently selected from hydrogen, alkyl, alkoxy, F, Cl, Br, I, CN, and NO2;
- wherein at least one of R′ and R″ is not hydrogen;
- and n represents the number of repeating groups.
