## Abstract The synthesis of poly(2,5‐dialkoxy‐__p__‐phenylene)s (PPP) by palladium‐catalyzed polycondensation of 2,5‐dialkoxy‐4‐bromophenylboronic acids is described. Number‐average degrees of polymerization of ca. 30 have been reached at best. The characterization of the polymers by NMR, IR, UV‐V
## Abstract Poly(2,5‐dipropargyloxy‐1,4‐phenylenevinylene) (PDPPV) and its copolymers were prepared as thin films via the organic‐soluble and water‐soluble precursor routes. Elimination and crosslinking reactions could be controlled by the temperature. Crosslinked PDPPV is stable up to 450°C. The c
