where Y1 and Y2 are, each independently, a bond, a -CR1=N-NR2- group, or a -CR3=N-N=CR4- group;
R, R', R", R1, R2, R3, and R4 comprise, each independently, H, an alkyl group, an alkenyl group, a heterocyclic group, an aromatic group, or a part of a ring group;
X1 and X2 are, each independently, a linking group;
T2 comprises a thiiranyl group, H, an alkyl group, an alkenyl group, or an aromatic group;
Ar comprises an aromatic group;
Z is a bridging group; and
n is a distribution of integers between 1 and 100,000 with an average value at least 2; and
(b) a charge generating compound.
Corresponding electrophotographic apparatuses and imaging processes are also described, as are polymeric charge transport compositions.
