  1. Two dibenzo[Def, Mno]chrysene-based polymeric semiconductors: Surprisingly opposite device performances in field-effect transistors and solar cells

    A new series of conjugated polymers containing dibenzo[def, mno]chrysene units, PTTC and PTVTC, were successfully designed and synthesized. Two polymers exhibited similar optical and electrochemical properties, but they behaved very differently when used in thin-film transistors and solar cells. The PTTC polymer showed higher charge transport ability, whereas the PTVTC polymer presented higher efficiency in photovoltaic cells.

  2. Study of the composition and morphology of new modifications of titanium-magnesium catalysts with improved properties in ethylene polymerization

    The new highly active supported Ti-Mg catalyst (TMC-M) with improved morphology has higher sensitivity to hydrogen as regulator of PE molecular weight and produce polymer with high bulk density. TMC-M has highly disordered crystal structure and contains alcohol as intercalate in MgCl2 interlayer structure. TMC-M has high specific surface area and small pore size after activation by AlEt3. These physicochemical properties of TMC-M seem to be the important factors determining the improved catalytic properties.

  3. Lactose-containing hydrogels for enzyme stabilization

    Article first published online: 21 APR 2016 | DOI: 10.1002/pola.28127

    A lactose-containing hydrogel stabilizes the enzyme Papain against heating and lyophilization leading to a retention of activity. Release kinetics of the enzyme, and swelling ratio and storage moduli of the gels, can be tuned by changing the comonomer composition used to prepare the gels.

  4. Synergistic effect of cellulose nanowhiskers reinforcement and dicarboxylic acids crosslinking towards polyvinyl alcohol properties

    Amit Kumar Sonker, Naveen Tiwari, Rajaram Krishna Nagarale and Vivek Verma

    Article first published online: 21 APR 2016 | DOI: 10.1002/pola.28129

    PVA and BCNW samples are crosslinked with diacids to demonstrate the synergy between the two processes, namely reinforcement and crosslinking. In addition to the synergistic effect, the effect of crosslinker (diacid) length on the properties of PVA is also studied in detail.

  5. Pendant groups fine-tuning thermal gelation of poly(ε-caprolactone)-b-poly(ethylene glycol)-b-poly(ε-caprolactone) aqueous solution

    Article first published online: 21 APR 2016 | DOI: 10.1002/pola.28134

    Thumbnail image of graphical abstract

    The thermal gelation behavior of PCL-PEG-PCL aqueous solution was finely tuned via the introduction of hydrophobic γ-(carbamic acid benzyl ester) and hydrophiphilic amino pendant groups. This pendant group modification approach supplied a platform to adjust various physicochemical properties of the aliphatic polyester hydrogels without sacrifice of the intrinsic properties of the polyesters, which could preferably facilitate biomedical application of the PEG/PCL hydrogels.
