A new route for the synthesis of soluble, alkoxy‐substitutedpoly(p‐phenylenevinylene) benzobisoxazoles has been developed. The target polymers can be prepared in three steps: the Lewis acid catalyzed condensation of corresponding diamino benzene diols with triethyl orthochloroacetate, the Arbuzov reaction of the resultant benzobisoxazole, and the Horner‐Wadsworth‐Emmons polymerization of 2,5‐dido
