  1. Autoacceleration and Cyclization Effects on Styrene/Divinylbenzene Copolymerization

    Vinícius N. Santos, Leandro G. Aguiar and Reinaldo Giudici

    Version of Record online: 25 AUG 2016 | DOI: 10.1002/mren.201600021

    The effect of cyclization reaction in styrene-divinylbenzene copolymerization is studied in diluted solution. Pendant double bond concentration is measured by Fourier transform infrared spectroscopy and the experimental results are interpreted by a kinetic model of this process. Rate constants for crosslinking and cyclization are estimated from the experiments.

  2. Origin of Chemical Composition of Ethylene/Propylene Copolymer Produced with Ziegler–Natta Catalyst

    Copolymer composition in Ziegler–Natta catalyzed ethylene/propylene copolymerization tends to be dependent on the yield rather than the nature of active sites. The ethylene consumption easily overcomes its supply due to the comonomer effect as well as the high reactivity and poor solubility of ethylene. Low-yield polymerization is essential to study the influence of the active site nature on the copolymerization.

  3. Synthesis of Narrow Molecular Weight Distribution Copolymers for ArF Photoresist Materials by Nitroxide Mediated Polymerization

    Zi Jun Wang, Kevin Wylie and Milan Marić

    Version of Record online: 22 AUG 2016 | DOI: 10.1002/mren.201600029

    Adamantyl-based methacrylic monomers are terpolymerized by NMP using low concentrations ≈5 mol% of various controlling comonomers in the initial mixture. Polymerizations are characterized by linear inline image versus conversion up to nearly 70% with low inline image. Low concentrations of styrenic controller comonomer do not affect the optical transparency (with exception of vinyl naphthalene) and thus these resins are promising for 193 nm photolithography resists.

  4. A Comprehensive Review on Controlled Synthesis of Long-Chain Branched Polyolefins: Part 3, Characterization of Long-Chain Branched Polymers

    Pingwei Liu, Weifeng Liu, Wen-Jun Wang, Bo-Geng Li and Shiping Zhu

    Version of Record online: 22 AUG 2016 | DOI: 10.1002/mren.201600012

    Long-chain branched polyolefins exhibit improved melt processability, such as higher melt strength and better shear thinning. In the previous papers, the catalyst systems and reaction conditions for the controlled synthesis of long-chain branched polyolefins have been reviewed. This paper summarizes the literatures pertinent to the precise characterization of long-chain branched polyolefins and provides perspectives about various characterization techniques.

  5. Continuous Pilot-Scale Tubular Reactor for Acrylic Acid Polymerization in Solution Designed Using Lab-Scale Rheo-Raman data (pages 354–363)

    Marie-Claire Chevrel, Sandrine Hoppe, Dimitrios Meimaroglou, Laurent Falk and Alain Durand

    Version of Record online: 19 AUG 2016 | DOI: 10.1002/mren.201500058

    A continuous pilot-scale tubular reactor equipped with CSE-X static mixers from Fluitec is designed for polymerization of acrylic acid in aqueous solution. Experimental results are satisfactorily described by the model of perfect plug-flow reactor. This work provides the first demonstration of applicability of CSE-X static mixer elements in a continuous process producing high molar mass water-soluble polymer.
