Nanostructures of thin films made of binary blends of diblock copolymers are investigated by atomic force microscopy (AFM) and grazing-incidence small-angle X-ray scattering (GISAXS). For the as-prepared thin films, microphase-separated nanostructures are obtained, and the high molar mass copolymer determines the orientation of the lamellae. After solvent vapor annealing, macrophase-separated nanostructures appear featuring parallel lamellae near the film surface and perpendicular ones in the bulk.
- Cu(II)-Mediated Atom Transfer Radical Polymerization of Methyl Methacrylate via a Strategy of Thermo-Regulated Phase-Separable Catalysis in a Liquid/Liquid Biphasic System: Homogeneous Catalysis, Facile Heterogeneous Separation, and Recycling

A strategy of thermo-regulated phase-separable catalysis (TPSC) is applied to the Cu(II)-mediated atom transfer radical polymerization (ATRP) of methyl methacrylate (MMA) in a p-xylene/PEG-200 biphasic system. It is a facile strategy involving successful separation and recycling of the catalyst complex from polymer products in situ. Well-defined PMMA with designable molecular weight and narrow molecular weight distribution can be obtained with this system, which may have strong potential for the industrial application of the ATRP technique.

Back Cover: Cellulose, the most abundant terrestrial biopolymer, can be dissolved efficiently in a mixture of acetone and a quaternary ammonium chloride. The properties of the resulting translucent cellulose solution may lead to new functional cellulose derivatives or enhance shaping processes. Further information can be found in the article by Marc Kostag, Tim Liebert, and Thomas Heinze* on page 1419.

Frontispiece: A supramolecular polymer gel which shows multiple-stimuli responsiveness and self-healing properties is prepared by multiple orthogonal interactions. The topology of the gel networks can be easily tuned from monomer to main-chain supramolecular polymer and then to supramolecular networks. Further information can be found in the article by Jiayi Zhan, Mingming Zhang, Mi Zhou, Bin Liu, Dong Chen, Yuanyuan Liu, Qianqian Chen, Huayu Qiu, and Shouchun Yin* on page 1424.

Front Cover: Rattle-like polymer capsules with multicores in one shell are facilely fabricated by polymerization based on oil-in-water Pickering emulsion with nano particle nucleation and phase separation in the oil phase. This work opens up a new route to fabricate multi-level capsules or spheres, which could find potential applications in controlled release, adsorption, and catalysis. Further information can be found in the article by Shengwen Zou, Yang Hu, and Chaoyang Wang* on page 1414.
