  1. Inline Turbidity Measurements of Batch Emulsion Polymerization

    Dimitrie Bloch, Peter Bröge and Werner Pauer

    Version of Record online: 20 FEB 2017 | DOI: 10.1002/mren.201600063

    Inline turbidity is shown as a tool to monitor optical properties in the process of emulsification as well as during batch emulsion polymerization. This technique can be used for the detection of the reaction start, to observe droplet formation, and to identify emulsion stability problems.

  2. Preparation of Forced Gradient Copolymers Using Tube-in-Tube Continuous Flow Reactors

    Simon Saubern, Xuan Nguyen, Van Nguyen, James Gardiner, John Tsanaktsidis and John Chiefari

    Version of Record online: 27 JAN 2017 | DOI: 10.1002/mren.201600065

    A perforated tube-in-tube reactor is used to prepare forced gradient co-polymers using the RAFT controlled radical polymerization method.

  3. Nitroxide-Mediated Polymerization of 2-Hydroxyethyl Methacrylate (HEMA) Controlled with Low Concentrations of Acrylonitrile and Styrene

    Wenwen Mei and Milan Maric

    Version of Record online: 25 JAN 2017 | DOI: 10.1002/mren.201600067

    Nitroxide-mediated polymerization with SG1/based initiators is used to prepare hydroxyethyl methacrylate (HEMA)-rich copolymers using a small fraction ≈10 mol% of comonomer, preferably acrylonitrile (AN). HEMA/AN copolymerizations exhibit linear degree of polymerization versus conversion with low dispersity (Đ = 1.3–1.4). The chain ends exhibit good fidelity, with HEMA/AN macroinitiators chain extending a second batch of monomers cleanly.

  5. Use of Online Spectroscopy to Control Polymerization in Industrial Processes

    Brenda Colegrove, Kishori Deshpande, Rich Harner, Liane Mikolajczyk, Serena K. Stephenson, J. D. Tate and John Weston

    Version of Record online: 20 JAN 2017 | DOI: 10.1002/mren.201600056

    Online spectroscopy lends itself very well to monitoring polymerization reactors because the data it provides are information rich and can be deployed using fiber optics for remote sampling process streams. Several industrial examples are provided, including application to polyethylene, polycarbonate, polyurethane, and polystyrene processes.
