      Front Cover: Reversibly coagulatable and redispersible polyacrylate latexes are prepared by emulsion (co)poly-merization of methyl methacrylate (MMA) using a polymeric surfactant, PDMAEMA-block-PMMA. The resulting PMMA latexes can be readily coagulated with a trace amount of caustic soda. The coagulated latex pastes, after washing, can also be redispersed into fresh water to form stable emulsions by CO2 bubbling with ultrasonication. The coagulation and redispersion processes are repeatable. Further details can be found in the article by Q. Zhang, G. Yu, W.-J. Wang,* B.-G. Li, and S. Zhu* on page 916.

      Back Cover: Alkene and alkyne functionalized reactive polymers provide a facile strategy of surface modification that can readily proceed with promising thiol-ene and thiol-yne coupling reactions. Designer surfaces are demonstrated by low-protein fouling surfaces on silver, titanium, stainless steel, glass, PMMA, and PDMS substrates, as well as using cysteine-containing functional peptides to manipulate cell attachments. Further details can be found in the article by J.-T. Wu, C.-H. Huang, W.-C. Liang, Y.-L. Wu, J. Yu, and H.-Y. Chen* on page 922.

    1. Alkene Metathesis – A Tool for the Synthesis of Conjugated Polymers (pages 886–910)

      Uwe H. F. Bunz, Dominic Mäker and Michael Porz

      Article first published online: 17 APR 2012 | DOI: 10.1002/marc.201200001

      Thumbnail image of graphical abstract

      Alkene metathesis is powerful in the synthesis of vinyl-bridged conjugated polymers. Using either ring-opening metathesis polymerization (ROMP) or ADMET (acyclic diene metathesis) poly(paraphenylenevinylene)s (PPVs), and polyacetylenes (PAs) can be prepared efficiently. The influence of monomer, catalyst, and choice of method upon the properties of the formed polymers are discussed in this review.

    1. Surface-Modifiable Free-Floating Films Formed by Multiway Connection of Collagen-Like Triple-Helical Peptides (pages 911–915)

      Shunsuke Matsui, Chisato M. Yamazaki and Takaki Koide

      Article first published online: 5 MAR 2012 | DOI: 10.1002/marc.201100764

      Thumbnail image of graphical abstract

      Square-millimeter-sized free-floating translucent films are formed in physiological buffer by multiway connections between biotinylated collagen-like triple-helical peptides and avidin. The film thicknesses can be controlled by the concentrations of the components, and the surfaces can be further modified by taking advantage of exposed biotin (or avidin) functionalities.

    2. Preparation of CO2/N2-Triggered Reversibly Coagulatable and Redispersible Polyacrylate Latexes by Emulsion Polymerization Using a Polymeric Surfactant (pages 916–921)

      Qi Zhang, Guoqiang Yu, Wen-Jun Wang, Bo-Geng Li and Shiping Zhu

      Article first published online: 5 APR 2012 | DOI: 10.1002/marc.201200033

      Thumbnail image of graphical abstract

      A polymeric surfactant (PDMAEMA-block-PMMA) was used to prepare reversibly coagulatable and redispersible PMMA latexes through RAFT (co)polymerization. The emulsions could be coagulated by N2 bubbling with gentle heating. The coagulated latex pastes after washing could also be redispersed into fresh water to form stable emulsions by CO2 bubbling with ultrasonication. The coagulation and redispersion processes were repeatable.

    3. Reactive Polymer Coatings: A General Route to Thiol-ene and Thiol-yne Click Reactions (pages 922–927)

      Jyun-Ting Wu, Chi-Hui Huang, Wei-Chieh Liang, Yen-Lin Wu, Jiashing Yu and Hsien-Yeh Chen

      Article first published online: 20 FEB 2012 | DOI: 10.1002/marc.201200011

      Thumbnail image of graphical abstract

      Vapor-deposited reactive polymer coatings provide a general route to support thiol-ene and thiol-yne reactions on a variety of substrate materials. Surface functions can be activated through a simple design of thiol-terminated molecules, and the corresponding responses are efficiently and accurately manipulated.

    4. Inverse Suspension Polymerization as a New Tool for the Synthesis of Ion-Imprinted Polymers (pages 928–932)

      Walid Meouche, Catherine Branger, Isabelle Beurroies, Renaud Denoyel and André Margaillan

      Article first published online: 21 FEB 2012 | DOI: 10.1002/marc.201200039

      Thumbnail image of graphical abstract

      Inverse suspension polymerization is used for the first time to produce ion- imprinted polymer beads. This facile approach leads to materials with high site accessibility and large adsorption capacities. The ratio between the functional monomer and the crosslinker plays an important role on the “imprinting effect” of the polymers.

    5. Facile Preparation of Polymeric Dimers from Amphiphilic Patchy Particles (pages 933–937)

      Fengyang Wang, Lin Cheng, Tianhong Chen, Dongsheng Zhu, Qiang Wen and Shaowu Wang

      Article first published online: 27 FEB 2012 | DOI: 10.1002/marc.201100787

      Thumbnail image of graphical abstract

      Uniform polymeric dimers are efficiently obtained via hydrophobic interactions from amphiphilic mixed-shell micelles under optimized conditions in selective solvent. These micelles are fabricated by non-covalent crosslinking methods. The results are fully characterized by scanning electron microscopy, transmission electron microscopy, dynamic light scattering, and Fourier transform infrared spectroscopy.

    6. In Situ Hetero End-Functionalized Polythiophene and Subsequent “Click” Chemistry With DNA (pages 938–942)

      Jungkyu K. Lee, Sangwon Ko and Zhenan Bao

      Article first published online: 21 FEB 2012 | DOI: 10.1002/marc.201100686

      Thumbnail image of graphical abstract

      A versatile synthetic approach for bifunctionalized polythiophenes is described. The active end-group further reacts with DNA via “click” chemistry to form a polythiophene/DNA hybrid structure. Engineering the end functionalization is meant not only to allow for the synthesis of novel block copolymers, but also to be a platform for molecular level study.

    7. Estimation of Self-Diffusion Coefficients of Small Penetrants in Semicrystalline Polymers Using Single-Sided NMR (pages 943–947)

      R. Kwamen, B. Blümich and A. Adams

      Article first published online: 2 MAR 2012 | DOI: 10.1002/marc.201100847

      Thumbnail image of graphical abstract

      An efficient way to measure proton self-diffusion coefficients (D) of small penetrant molecules in semicrystalline polymers with different shapes and sizes and by using unilateral NMR is introduced. One-dimensional profiles of D across plates of semicrystalline polymers with several millimeter thickness and a heterogeneous structure are reported for the first time.
