A polymer having two different sets of repeat units consisting essentially of: Additionally, in the polymer R1 can be selected from the group consisting of alkyl group, alkoxy group, aryl groups and combinations thereof. In the polymer, n and m can be greater than 1.In the polymer, x and y can be different from each other and independently selected from the group consisting of: an alkoxy group, a substituted alkoxy group, an aryl group, an alkyl group, a substituted alkyl group, where y=1-3, where y=0-12, where R2 is selected from the group consisting of H, alkyl groups, and aryl groups, where R3 is selected from the group consisting of H, alkyl groups, and aryl groups, where R4 and R5 are independently selected from the group consisting of H, alkyl groups, and aryl groups, —NR6R7 where R6 and R7 are independently selected from the group consisting of H, alkyl groups, and aryl groups.
