  1. Synthesis of degradable molecular brushes via a combination of ring-opening polymerization and click chemistry

    Yi Shi, Xiaofeng Wang, Robert W. Graff, William A. Phillip and Haifeng Gao

    Article first published online: 23 JUL 2014 | DOI: 10.1002/pola.27307

    Molecular brushes with an acid-degradable backbone and densely-grafted side chains (2 side chains per backbone repeating unit) are synthesized using an efficient grafting-onto method. The incorporated side chains vary from homopolymers to block copolymers and grafted polymers, and the produced molecular brushes can be degraded completely into linear polymers. When a mixture of side chains are used, the amphiphilic hetero-grafted molecular brushes can assemble in water and form either spherical micelles or hollow vesicles depending on sample compositions.

  2. Synthesis and photoluminescence behaviors of anthracene-layered polymers

    Yasuhiro Morisaki, Tatsuya Nakano and Yoshiki Chujo

    Article first published online: 23 JUL 2014 | DOI: 10.1002/pola.27306

    Aromatic-ring layered polymers consisting of layered anthracenes and fluorescence quenchers at the polymer chain-ends are designed and synthesized. Photoluminescence behaviors show that the polymers act as single molecular wires.

  3. Postpolymerization modification of reactive polymers derived from vinylcyclopropane. III. Polymer sequential functionalization using a combination of amines with alkoxyamines, hydrazides, isocyanates, or acyl halides

    Denis Hervé Seuyep Ntoukam, Gerrit Albert Luinstra and Patrick Theato

    Article first published online: 23 JUL 2014 | DOI: 10.1002/pola.27311

    1,1-Disubtitutedvinylcyclopropane were used to prepare a polymer with two readily functionalizable side chain consisted of pentaflourophenyl and ketone. Sequential post-modification was successfully performed and a library of double functional polymers was prepared with a precise positioning of the functionality in the polymer backbone.

  4. Anionic alternating copolymerization of α-arylacrylates with methyl methacrylate: Effect of monomer sequence on fluorescence

    Yasuhiro Kohsaka, Eiji Yamaguchi and Tatsuki Kitayama

    Article first published online: 22 JUL 2014 | DOI: 10.1002/pola.27305

    Thumbnail image of graphical abstract

    Anionic polymerizations of acrylates possessing various aromatic fluorophores in α-substituents were investigated as well as the properties of the obtained polymers. Copolymerization of α-(2-naphthyl)acrylate and α-(2-fluorenyl)acrylate with methyl methacrylate (MMA) afforded alternating copolymers. Although the homopolymer of α-(2-fluorenyl)acrylate exhibited strong excimer emission in diluted chloroform solution, strong monomer emission was observed from the corresponding alternating copolymer, demonstrating the sequence-control effect on the emission properties.

  5. Control of microstructure and gradient property of polymer network by photopolymerizable silicone-containing nanogel

    Cong Chen, JianCheng Liu, Fang Sun and Jeffrey W. Stansbury

    Article first published online: 22 JUL 2014 | DOI: 10.1002/pola.27309

    Thumbnail image of graphical abstract

    The silicone-containing nanogel with self-floating ability can not only reduce polymerization stress, but also spontaneously form a gradient distribution of concentration, leading to a gradient change in the thermal stability of the polymer and a more hydrophobic surface with altered surface microstructure.
