      Front Cover: A simple and mild approach for encapsulation of reactive azide-terminated polyisobutylene in nanocontainers of poly(vinyl formal) is reported. The core-shell nanoparticles can be visualized directly in fluorescence microscopy by labelling the two polymers with different dyes or extracting the core polymer with a selective solvent. Further details can be found in the article by Y. Zhao, D. Döhler, L.-P. Lv, W. H. Binder, K. Landfester, and D. Crespy* on page 198.

    1. Synthesis of Amphiphilic Polymers Based on Fatty Acids and Glycerol-Derived Monomers – A Study of Their Self-Assembly in Water (pages 131–139)

      Jefferson Rotta, Phuoc Dien Pham, Vincent Lapinte, Rédouane Borsali, Edson Minatti and Jean-Jacques Robin

      Version of Record online: 26 NOV 2013 | DOI: 10.1002/macp.201300483

      Various biobased compounds are polymerized to give amphiphilic polymers according to a simple procedure. Telomerization of glycerin-derived acrylate with mercaptan-modified fatty acids as telogen agents is studied, leading to telomers capable of self-assembling into nanosized spherical particles in aqueous solution.

    2. Collective Dynamics and Transient Behavior of Partially Hydrophobic Hyaluronic Acid Chains (pages 140–147)

      Ivana Finelli, Ester Chiessi, Letizia Oddo, Devis Galesso, Davide Renier and Gaio Paradossi

      Version of Record online: 29 NOV 2013 | DOI: 10.1002/macp.201300503

      Fluorescence recovery after photobleaching shows dramatic differences in the diffusional behavior of hyaluronic acid (HA) and partially hydrophobized hyaluronic acid (HYADD4): in HA, the fluorescence is recovered after about 50 s, whereas in HYADD4 the bleach remains after several minutes. The polymer concentration, Cp = 0.8% (w/v), is the same in both experiments.

    3. Direct Pyrolysis - Mass Spectrometry Analysis of Thermal Degradation of Thio-Click-Modified Poly(2-oxazoline) (pages 148–152)

      Nurcan Atilkan, Helmut Schlaad, Yusuf Nur and Jale Hacaloglu

      Version of Record online: 6 DEC 2013 | DOI: 10.1002/macp.201300524

      Comprehensive DP-MS analysis of the thermal degradation characteristics of thio-click-modified poly[2-(3-butenyl)-2-oxazoline] (PBOX), carrying glucose and/or perfluoroalkyl groups is carried out. Significant changes in the thermal stability and thermal degradation products are observed depending on the structure of the side chain.

    4. Crystallization of Poly(vinylidene fluoride) in Blends with Poly(methyl methacrylate-co-methacrylic acid) Copolymers (pages 153–162)

      Forrest A. Landis, Stephen R. March Jr., Dakshinamoorthy Deivasagayam and Robert T. Mathers

      Version of Record online: 6 DEC 2013 | DOI: 10.1002/macp.201300535

      Poly(methyl methacrylate-co-methacrylic acid) (PMMA-co-MAA) copolymers are synthesized and blended with poly(vinylidene fluoride) (PVDF). It is observed that the crystallization rate of PVDF is reduced when the MAA content is <5.5 mol% in the copolymer due to enhanced intermolecular interactions. At higher MAA contents, the growth of the PVDF crystallites in the blend approach that of pure PVDF.

    5. Dual-Functional PEI–Poly(γ-Cholesterol-l-Glutamate) Copolymer for Drug/Gene Co-delivery (pages 163–170)

      Jinkun Zhang, Dailong Fang, Qing Ma, Zhiyao He, Ke Ren, Rui Zhou, Shi Zeng, Bo Li, Lili He, Gu He and Xiangrong Song

      Version of Record online: 24 NOV 2013 | DOI: 10.1002/macp.201300551

      Thumbnail image of graphical abstract

      A series of novel amphiphilic PEI-poly(γ-cholesterol-L-glutamate) (PEI-PCHLG) copolymers are synthesized and characterized. One of PEI-PCHLG copolymers can self-assemble into micelles. The PCHLG block assembles into micelles with high drug entrapment, and the grafted PEI block can act as a hydrophilic section exposed outside the micelles, which are capable of carrying genes. Thus PEI-PCLG copolymers are potential carriers for drug/gene co-delivery.

    6. 1,4-Bisbenzil: Visible-Light- and Heat-Assisted Crosslinking of Polystyrene Films (pages 171–176)

      Ivan Lukáč, Csaba Kósa and Branislav Husár

      Version of Record online: 4 NOV 2013 | DOI: 10.1002/macp.201300553

      Thumbnail image of graphical abstract

      A novel method of crosslinking of polystyrene films by 1,4-bisbenzil is presented. The crosslinking occurs in two steps: in the first step, polystyrene film doped with 1,4-bisbenzil is irradiated with visible light (λ > 400 nm) in the presence of oxygen. In the second step, photoperoxidized polystyrene is subsequently thermal treated to cause crosslinking.

    7. Convenient Synthesis of a Polyester-co-Polyether Block for Assembling Biocompatible Hyperbranched Macromolecules (pages 177–181)

      Igor Elkin and Patrice Hildgen

      Version of Record online: 29 NOV 2013 | DOI: 10.1002/macp.201300578

      Thumbnail image of graphical abstract

      Synthesis of a novel multifunctional polyester-co-polyether (PEPE) block based on asymmetrically substituted pentaerythritol, succinic acid, and tetraethylene glycol is reported. The proposed reaction conditions allow selective preparation of the product in high overall yield. The block is used in the assembly of PEPE dendrons of second generation by classical step-by-step and alternative “block by block” strategies.

    8. The Influence of RAFT on the Microstructure and the Mechanical Properties of Photopolymerized Poly(butyl acrylate) Networks (pages 182–189)

      Rouven Henkel and Philipp Vana

      Version of Record online: 10 DEC 2013 | DOI: 10.1002/macp.201300581

      Networks of butyl acrylate are photopolymerized both in the presence and absence of an RAFT agent. The Young's moduli of the RAFT networks are lower than those of the conventionally obtained networks. With an increasing amount of RAFT agent, the Young's modulus decreases and the strain at break values increase, respectively. The network density, the apparent molar mass of the network chains, and the swelling show significant differences between RAFT networks and conventionally obtained networks.

    9. Surface-Initiated RAFT/MADIX Polymerization on Xanthate-Coated Iron Oxide Nanoparticles (pages 190–197)

      Agnieszka Z. Wilczewska and Karolina H. Markiewicz

      Magnetite–polymer core–shell structures are materials that hold significant promise for the development of many branches of science and industry. The reversible addition-fragmentation chain transfer/macromolecular design via interchange of xanthates (RAFT/MADIX) polymerization is an easy way to obtain stable polymer-coated magnetic nanoparticles (MNPs) with controlled architecture and composition of the organic shell, and therefore with controlled properties of the target nanostructures.

    10. Facile Phase-Separation Approach to Encapsulate Functionalized Polymers in Core–Shell Nanoparticles (pages 198–204)

      Yi Zhao, Diana Döhler, Li-Ping Lv, Wolfgang H. Binder, Katharina Landfester and Daniel Crespy

      Version of Record online: 13 NOV 2013 | DOI: 10.1002/macp.201300558

      Reactive polymers for self-healing materials are encapsulated with a high efficiency in polymer nanocontainers. The concentration of surfactant plays a major role in the encapsulation efficiency.

    11. Polymer Melting Kinetics Appears to be Driven by Heterogeneous Nucleation (pages 205–209)

      Version of Record online: 17 DEC 2013 | DOI: 10.1002/macp.201300636

      By using the well-known Kissinger plot, ln(β/Tp2)vs. Tp−1, a temperature dependence of the effective activation energy for polymer melting can be evaluated. A simple theoretical treatment of this dependence in the framework of a nucleation model allows nucleation parameters to be obtained that consistently indicate that polymer melting is driven by heterogeneous nucleation.

    12. Swelling Behaviors of Poly(N-isopropylacrylamide) Nanosized Hydrogel Particles/Poly(vinyl alcohol)/Water Systems: Effect of the Degree of Hydrolysis of PVA (pages 210–216)

      Sung Min Kim, Ji Su Choi and Young Chan Bae

      Version of Record online: 17 DEC 2013 | DOI: 10.1002/macp.201300662

      Thumbnail image of graphical abstract

      The swelling behaviors of poly(N-isopropylacrylamide) (PNIPA) gel particles are measured in aqueous poly(vinyl alcohol) (PVA) solutions. The absorption of PVA is influenced by the degree of hydrolysis of the PVA. Model parameters are obtained from corresponding liquid-liquid equilibria (LLE) data or experimental conditions to give physical meaning. In addition, various equilibrium properties are presented using the same parameters.
