    Front Cover: Ordering phenomena in polymers are core principles in biological and synthetic macromolecules. A precision poly(olefin) containing a beta-turn mimic as a repetitive folding-constraint after every 16 methylene units is designed, which enables the constrained crystallization of the methylene units to be studied within the obtained polymer. Further details can be found in the article by S. Reimann, U. Baumeister, and W. H. Binder* on page 1963.

  5. Enhancement of Anhydrous Proton Conductivity of Poly(vinylphosphonic acid)–Poly(2,5-benzimidazole) Membranes via In Situ Polymerization

    Polymer electrolyte membranes (PEMs) are synthesized via in situ polymerization of vinylphosphonic acid (VPA) within a poly(2,5-benzimidazole) (ABPBI) matrix. Physicochemical characterization suggests the complexation between ABPBI and PVPA and the formation of homogeneous polymer blends. Considerable proton conductivities of up to 0.002 S cm−1 are achieved in the anhydrous state (150 °C), which indicates significant improvements (103–104 times) over the physically blended samples.
