  1. Polymerization of Norbornene Using Chiral Bis(phenolate) Zirconium Catalysts

    Marie Tschage, Seungwhan Jung, Thomas P. Spaniol and Jun Okuda

    Article first published online: 30 SEP 2014 | DOI: 10.1002/marc.201400386

    Norbornene is polymerized by both racemic and enantiopure zirconium bis(phenolate) catalysts with an (OSSO)-type ligand. Hydrooligomerization is performed leading to crystalline tetramers, which show 2,3-cis connections. Comparison of hydrooligomers and deuterooligomers confirms this enchainment without C7-linkages. The optical activity of the polymers and oligomers is investigated.

    Nano-Stereocomplexation of Polylactide (PLA) Spheres by Spray Droplet Atomization

    Veluska Arias, Karin Odelius and Ann-Christine Albertsson

    Article first published online: 29 SEP 2014 | DOI: 10.1002/marc.201400374

    A direct and efficient method for the preparation of stereocomplexed high-molecular-weight polylactide (PLA)-based spherical nanoparticles by spray droplet atomization from polymeric solution is developed. These nanoparticles are expected to function as renewable materials in PLA-based nanocomposites and potentially as more stable drug delivery carriers.

  3. Self-Storage: A Novel Family of Stimuli-Responsive Polymer Materials for Optical and Electrochemical Switching

    Yixiao Dong, Chaocan Zhang, Lili Wu, Yanjun Chen and Yuanyuan Hu

    Article first published online: 25 SEP 2014 | DOI: 10.1002/marc.201400356

    Stimuli-responsive materials are fabricated by rising entropic effects to “disperse” liquid droplets in the polymer matrix. The responsive features show great promises for applications in solid devices, especially for optical smart windows and responsive solid electrolytes.

  4. Self-Assembly of Conjugated Units Using Metal-Terpyridine Coordination

    Yang Gao, Deepa Rajwar and Andrew C. Grimsdale

    Article first published online: 25 SEP 2014 | DOI: 10.1002/marc.201400225

    Materials with greatly enhanced physical and optical properties can be made by zinc-ion coordination of conjugated units bearing 2-, 3-, or 4-terpyridine units to form 1D, 2D, and 3D supramolecular polymers and networks. These materials show promise in light harvesting and nonlinear optical applications.

  5. Tailored Thiol-Functional Polyamides: Synthesis and Functionalization

    Stefan Mommer, Helmut Keul and Martin Möller

    Article first published online: 25 SEP 2014 | DOI: 10.1002/marc.201400377

    A bis(thiolactone) is synthesized and its reactivity toward amines is analyzed. Next, it is utilized as A,A-type monomer with two B,B-type comonomers (diamines with different content of each) to form polyamides with thiol side groups bearing different thermal properties. The thiol side groups are functionalized via postpoly­merization modification by Michael addition to acrylates.
