1. A composition, comprising
a polymer of Formula (I) wherein: R1, R2, R3, and R6 are each independently selected from H and C1-6 alkyl; R4 and R5 are each independently selected from H, C1-6 alkyl, C1-6 haloalkyl, C1-6 alkoxy, and C1-6 haloalkoxy; X is a multivalent linker selected fromwherein RA and RB are each independently selected from H and C1-6 alkyl;
L1 is each independently —C1-4 alkylene-O—; n is each independently an integer from 0 to 10,000, provided that the sum of all n in Formula (I) is not 0; and m is 2, 3, or 4.
