Abstract
A method of combining different materials to produce the polymer In this polymer X1, X2, X3, and X4 are independently selected from the group consisting of: F, Cl, H, and combinations thereof. Additionally, in this polymer R15, R16, R17, and R18 are independently selected from the group consisting of: F, Cl, H, and combinations thereof. Finally, in this polymer R1, R2, R3, R4, R5, R6, R7, and R8 are independently selected from unsubstituted branched alkyls with 1 to 60 carbon atoms unsubstituted or substituted branched alkyls with 1 to 60 carbon atoms and unsubstituted or substituted linear alkyls with 1 to 60 carbon atoms.
