- Anionic Polysaccharides as Templates for the Synthesis of Conducting Polyaniline and as Structural Matrix for Conducting Biocomposites
Ann-Sofie Leppänen, Chunlin Xu, Jun Liu, Xiaoju Wang, Markus Pesonen and Stefan Willför

Polysaccharide/polyaniline biocomposites are synthesized using a green, chemoenzymatic procedure. Anionic polysaccharides, for example, naturally occurring κ-carrageenan, and TEMPO-oxidized cellulose, are used as templates in laccase-catalyzed polymerization of aniline.
- Facile Polymer Functionalization of Hydrothermal-Carbonization-Derived Carbons

Facile “graft-to” cycloaddition-mediated polymer functionalization of hydrothermal carbonization (HTC)-derived materials is carried out by use of a dienophile-functionalized polymer. Masked maleimide terminated poly(ethylene glycol) (PEG) is used as a model dienophile containing polymer to graft onto the surface of the HTC material. Analysis of PEGylated carbons (Fourier transform infrared, elemental analysis, X-ray photoelectron spectroscopy, and dispersion studies) all indicate the successful surface modification.
- Water Plasticizes Only a Small Part of the Amorphous Phase in Nylon-6
Nicolaas Reuvers, Hendrik Huinink and Olaf Adan

How much of the amorphous phase of a nylon-6 film is affected by water at room temperature far below the glass transition temperature and will take part in water transport? In this study nylon films are saturated with H2O/D2O and investigated with NMR relaxometry. Furthermore, the relaxation curves reveal that above a moisture content of 4% a mobile type of water molecules is present in the nylon matrix.
- Poly(2-vinylpyridine)-block -Poly(ϵ-caprolactone) Single Crystals in Micellar Solution
Mei Su, Haiying Huang, Xiaojing Ma, Qian Wang and Zhaohui Su
Article first published online: 10 MAY 2013 | DOI: 10.1002/marc.201300218
Single crystals of uniform shape and size in large quantities can be obtained via self-assembly of a coil-crystalline block copolymer by simply adding a selective solvent into the copolymer solution.
- Polypeptoids by Living Ring-Opening Polymerization of N-Substituted N-Carboxyanhydrides from Solid Supports
Niklas Gangloff, Corinna Fetsch and Robert Luxenhofer
Article first published online: 10 MAY 2013 | DOI: 10.1002/marc.201300269
Nucleophilic living ring-opening polymerization from solid-phase synthesis resins allows for the synthesis of highly defined polypeptoids. Multi-block copolymers are accessible via the successive monomer addition due to the stable propagating species. This new approach represents the missing link between solid-phase peptoid synthesis and solution-phase living nucleophilic polymerization of polypeptoids.
