  1. Condensed Low-Volatile Alcohol Droplet-Directed Uniform Pore Formation on Polystyrene Films

    Zheng-Hui Wang, Wei Cheng, Cai-Hong Liu, Jun Ma and Ji Li

    Article first published online: 25 JUN 2015 | DOI: 10.1002/macp.201500139

    A method for generating uniform pores of tunable size on polystyrene films is demonstrated. Low-volatile alcohol droplets condensed from polymer solutions are used to template the precipitation of polystyrene. The property of the low-volatile alcohol additive and the polystyrene concentration largely influence the film pore size.

  2. One-Pot Formation of ZnO-graft-Poly(d,l-Lactide) Hybrid Systems via Microwave-Assisted Polymerization of d,l-Lactide in the Presence of ZnO Nanoparticles

    Heriberto Rodríguez-Tobías, Graciela Morales, Amelia Olivas and Daniel Grande

    Article first published online: 25 JUN 2015 | DOI: 10.1002/macp.201500171

    An original and straightforward approach to ZnO-graft-poly(d,l-lactide) hybrid systems is thoroughly investigated. Such polymer-based hybrids are obtained by a one-pot procedure in which the corresponding monomer and ZnO nanoparticles are subjected to microwave irradiation in toluene for relatively short polymerization times.

  3. On the Homogeneity of Metallocene Ethylene–Propylene Copolymers as Investigated by Multiple Fractionation Techniques

    Mohau Justice Phiri, Anita Dimeska and Harald Pasch

    Article first published online: 18 JUN 2015 | DOI: 10.1002/macp.201500135

    A remarkably high chemical heterogeneity is found in ethylene–propylene copolymers synthesized by metallocene catalysts by preperation-temperature rising elution fractionation. Analysis of these fractions by several advanced methods including high-temperature high performance liquid chromatography indicates that the same TREF fractions from different samples have distinctively different chemical compositions.

  4. Synthesis and Characterization of Four-Arm Star Polystyrene Based on a Novel Tetrafunctional RAFT Agent

    Trevor Gavin Wright, Wolfgang Weber, Helen Pfukwa and Harald Pasch

    Article first published online: 18 JUN 2015 | DOI: 10.1002/macp.201500164

    Reversible addition fragmentation chain transfer (RAFT) polymerization is used to prepare four-arm star polystyrenes from a novel tetrafunctional RAFT agent. Advanced characterization using spectroscopic and separation methods is performed to confirm the formation of four-arm star topologies.
