    In this paper, novel polyaspartamide–polylactide graft copolymers are synthesized with suitable structural and functional properties for the realization of fluorescent nanoparticles with potential in imaging applications by following easy scaling up and repeatable processes.

    RAFT dispersion polymerization is a versatile and efficient tool to prepare core-shell particles of various morphologies by polymerization-induced self-assembly. This article reviews recent developments in this field, critically comments on them, and gives an outlook on further expected developments. It provides guidelines for non-experts by highlighting important aspects that must carefully be considered when planning the preparation of core-shell nanoobjects using this approach.

  3. Up to 100% Improvement in Dynamic Nuclear Polarization Solid-State NMR Sensitivity Enhancement of Polymers by Removing Oxygen

    High-field dynamic nuclear polarization is a powerful technique for increasing the sensitivity of solid-state NMR experiments on polymers. This work shows that removing the absorbed oxygen from polymer samples of varying molecular weights may provide up to a two-fold increase in sensitivity (hence a four-fold reduction in experimental time).

  4. Kinetically Enhanced Approach for Rapid and Tunable Self-Assembly of Rod–Coil Block Copolymers

    Chun-Chih Ho, Shang-Jung Wu, Shih-Hsiang Lin, Seth B. Darling and Wei-Fang Su

    Article first published online: 21 MAY 2015 | DOI: 10.1002/marc.201500161

    A kinetically enhanced approach to rapidly process rod–coil block copolymers into highly ordered nanostructures is demonstrated by introducing a selective plasticizer into the copolymers during annealing. With the assistance of 3-dodecylthiophene (3DDT), the P3DDT-b-PMMA can reach its thermodynamic equilibrium and obtain ordered structures at 140 °C in 1 h while 48 h at 200 °C are required without 3DDT.

  5. Responsive Polymer-Based Assemblies for Sensing Applications

    Xue Li, Yongfeng Gao and Michael J. Serpe

    Article first published online: 20 MAY 2015 | DOI: 10.1002/marc.201500066

    The fabrication of responsive polymer-based photonic materials and their ability to detect a variety of stimuli is reviewed. Emphasis is placed on hydrogels and microgels, particularly poly (N-isopropylacrylamide)-based materials. In each example, the responsive polymer is either used to provide structure, or acts as a matrix to secure other structured materials. The structure is what imparts color to the materials, which can be tuned by the responsive polymers. Many examples of such systems are detailed, with a particular focus on responsive polymer-based etalons.
