We prepared a rigid, chiral polymer (1) from optically active hydrobenzoin‐based subunits. Nonracemic monomer units 6 and 8 were prepared by asymmetric dihydroxylation (AD) methodology and polymerization was carried out under Sonagashira coupling conditions. Polymer 1 was obtained in good yield with a molecular weight M n = 5,100 (PDI = 2.3). Modeling suggests that polymer 1 could form a stable helical mainchain conformation in solution or the solid state. The chiroptical data of the polymer and a low‐molecular weight model compound (9) are compared. Chirality 14:258–263, 2002. © 2002 Wiley‐Liss, Inc.
