1. A composition comprising an amorphous (co)polymer comprising one or more repeat units, whereinp and q are independently selected from integers from 0 to 10,000, providing that at least one of p and q is greater than 0;
- R is selected from the group consisting of H and R3;
R1 is selected from a group consisting of H, and substituted and unsubstituted alkyl;
R2 is selected from a group consisting of H, OH, R3, OR3, COOR3, and COOR4;
R3 comprises an electrochromic group;
at least one of R and R2 in at least one repeat unit per polymer chain is OR3, R3 or COOR3;
R4 is selected from a group consisting of H, Na, and K;
A is selected from a group consisting of O and NR′
; and
R′
is selected from a group consisting of H and substituted and unsubstituted alkyl.
