18-Jan-2018 | Luis A. Clementi, Romina B. Suvire, Francisco G. Rossomando, Jorge R. Vega, Macromolecular Reaction Engineering, 2018
Abstract To improve the quality of industrial nitrile rubbers, the copolymer chemical composition, pA(t), should ideally be kept constant along the reaction. This work proposes a closed‐loop control strategy for the semibatch operation of the reactor with the aim of regulating pA(t) within a ...
15-Jan-2018 | Wei Zhang, Jian Ye, Binbo Jiang, Jingdai Wang, Zuwei Liao, Zhengliang Huang, Yongrong Yang, Zhibin Ye, Macromolecular Reaction Engineering, 2018
Abstract To reduce the simultaneous production of insoluble polymers during the bis(imino)pyridyl iron‐catalyzed ethylene oligomerization, in this study, p‐BrPhOH (4‐bromophenol) has been chosen as the most optimal modifier for the production of linear α‐olefins. It is found that the polymer ...
19-Dec-2017 | David Victoria‐Valenzuela, Jorge Herrera‐Ordonez, Antonio Arcos‐Casarrubias, Humberto Vazquez‐Torres, Macromolecular Reaction Engineering, 2017
Abstract The kinetics of bulk free‐radical polymerizations of n‐butyl methacrylate (n‐BMA), iso‐butyl methacrylate (i‐BMA), and tert‐butyl methacrylate (t‐BMA) are studied by differential scanning calorimetry and with the aid of a mathematical model previously reported by the authors. In all ...
16-Aug-2017 | Joris J. Haven, Neomy Zaquen, Maarten Rubens, Tanja Junkers, Macromolecular Reaction Engineering, 2017
Front Cover: Microreactor technology in combination with a high‐resolution mass spectrometer allows for on‐line “nonstop” analysis. The kinetics of n‐butyl acrylate polymerizations are studied for a wide range of temperatures and residence times. Via adjustment of flow rates in the reactor, ...

28-Jul-2017 | Jie Jiang, Wen‐Jun Wang, Bo‐Geng Li, Shiping Zhu, Macromolecular Reaction Engineering, 2017
Chain transfer reactions widely exist in the free radical polymerization and controlled radical polymerization, which can significantly influence polymer molecular weight and molecular weight distribution. In this work, the chain transfer reactions in modeling the reversible ...
19-Jun-2017 | Wenwen Mei, Milan Maric, Macromolecular Reaction Engineering, 2017
Front Cover: Nitroxide mediated polymerization (NMP) with SG1/based initiators is used to prepare hydroxyethyl methacrylate (HEMA)‐rich copolymers using a small fraction ≈ 10 mol% of co‐monomer, acrylonitrile (AN). HEMA/AN copolymerizations exhibit linear degree of polymerization versus ...
08-Jun-2017 | Liang Xiang, Wen‐Jun Wang, Bo‐Geng Li, Shiping Zhu, Macromolecular Reaction Engineering, 2017
Solution reversible addition fragmentation chain transfer (RAFT) polymerization of butyl acrylate in 50 wt% toluene, initiated with 2,2′‐azobisisobutyronitrile and mediated with 3‐benzyltrithiocarbonyl propionic acid, is carried out in a tube reactor of 1.65 mm inner diameter. The tube reactor ...
06-Jun-2017 | Alexandr Zubov, Omar Naeem, Svein Olav Hauger, Ala Bouaswaig, Fredrik Gjertsen, Peter Singstad, Klaus‐Dieter Hungenb ..., Macromolecular Reaction Engineering, 2017
Due to hardening competition and increased focus on resource efficiency, efforts are made to develop advanced industrial optimization and control systems with the goal to shift the (semi‐)batch production from recipe‐based to a state‐based approach. This study illustrates the steps needed for ...
31-May-2017 | Jared Cocke, Sebastian Maaß, Macromolecular Reaction Engineering, 2017
Recent studies have revealed unexpected developments in drop size by only small changes in the geometrical constraints of batch vessels used for suspension polymerization. The effect of the dispersed phase fraction, surfactant concentration, as well as baffle length on the evolving drop size ...
