- Synthesis and structure–property relationship of carbazole-alt-benzothiadiazole copolymers
Jules Oriou, Feifei Ng, Georges Hadziioannou, Cyril Brochon and Eric Cloutet
Article first published online: 18 APR 2015 | DOI: 10.1002/pola.27660
Four π-conjugated copolymers based on carbazole and benzothiadiazole (PCBT) were prepared by Suzuki cross-coupling reaction. Their structures differed by linkage position and geometry of the solubilizing chain on the carbazole subunits. These organic materials were characterized and showed promising properties for organic electronics applications. The differences in structure were shown to influence the optical properties.

Hyperbranched polytriazineis used to modify reduced graphene oxide, making it amphipathic and improving its distribution in polymer composites. In turn, this greatly improves the thermal stability and electrical conductivity of its polymer composites as compared with unmodified graphene oxide composites.
- Understanding of nanogels swelling behavior through a deep insight into their morphology
Aintzane Pikabea, Garbiñe Aguirre, Jose I. Miranda, Jose Ramos and Jacqueline Forcada
Article first published online: 18 APR 2015 | DOI: 10.1002/pola.27653
The morphology and swelling behavior of biocompatible and dual-stimuli-responsive nanogels crosslinked with different crosslinkers were analyzed and related by combining the Flory–Rehner theory with 1H-NMR and PCS data.
- A benign initiating system for cationic polymerization of isobutyl vinyl ether: Silver salt/aryl(alkyl) halide/lewis base
Li Lin, Guangyou Zhang, Koichi Kodama, Mikio Yasutake and Takuji Hirose
Article first published online: 18 APR 2015 | DOI: 10.1002/pola.27656
Aryl(alkyl) halides and silver salts were studied as an ecofriendly initiating system for cationic polymerization of isobutyl vinyl ether (IBVE). Me2S was shown to be an effective Lewis base (LB) for controlling the reaction. Detailed study of various benzyl cations and the order of reagent addition showed that the reaction was controlled by the steric and electronic features of the benzyl halides, LBs, and IBVE. A plausible reaction mechanism was proposed.
- A new route to atactic polypropylene: The second life of premetallocene homogeneous polymerization catalyst
Yury V. Kissin, Laura A. Rishina, Svetlana S. Lalayan and Vadim G. Krasheninnikov
Article first published online: 17 APR 2015 | DOI: 10.1002/pola.27651
Ternary Ti(Oiso-Pr)4 - AlEt2Cl/MgBu2 catalyst polymerizes propylene at 30–50 °С to a predominantly amorphous atactic polymer. The 13C NMR spectrum of the heptane-soluble fraction of the polymer consists of signals of various stereo-irregular pentads and heptads; its [mmmm] = 0.21.
