Special Issue Information

Dear Colleagues,

Reversible deactivation radical polymerization (RDRP) has made a tremendous impact in polymer science, empowering us to finely control the growth of polymer chains, thus realizing well-defined, valuable materials. One hundred years after Staudinger’s “macromolecular hypothesis”, polymer scientists confront important challenges, which include shifting from fossil-based raw materials, designing degradable plastics, and making sequence-defined polymers and safe polymer-based energy devices. RDRP is greatly contributing to solving these challenges and leading innovation in polymer and material science. The underlying requirement is the development of simple, sustainable, and scalable processes to address environmental and societal needs.

This Special Issue aims to collect original research and reviews presenting recent advances in RDRP processes with a focus on sustainability, simplification, and predictive methods. Topics include, but are not limited to:

Sustainable catalysts/chain transfer systems;
Temporal and spatial control;
Oxygen tolerance;
Flow chemistry;
Dispersed media;
Polymerization modeling and simulation.

Manuscript Submission Information

Manuscripts should be submitted online at www.mdpi.com by registering and logging in to this website. Once you are registered, click here to go to the submission form. Manuscripts can be submitted until the deadline. All papers will be peer-reviewed. Accepted papers will be published continuously in the journal (as soon as accepted) and will be listed together on the special issue website. Research articles, review articles as well as short communications are invited. For planned papers, a title and short abstract (about 100 words) can be sent to the Editorial Office for announcement on this website.

Submitted manuscripts should not have been published previously, nor be under consideration for publication elsewhere (except conference proceedings papers). All manuscripts are thoroughly refereed through a single-blind peer-review process. A guide for authors and other relevant information for submission of manuscripts is available on the Instructions for Authors page. Processes is an international peer-reviewed open access monthly journal published by MDPI.

Please visit the Instructions for Authors page before submitting a manuscript. The Article Processing Charge (APC) for publication in this open access journal is 2000 CHF (Swiss Francs). Submitted papers should be well formatted and use good English. Authors may use MDPI's English editing service prior to publication or during author revisions.

Exploring Electrochemically Mediated ATRP of Styrene

by Francesco De Bon, Gian Marco Carlan, Enrico Tognella and Abdirisak Ahmed Isse

Abstract

Electrochemically mediated atom transfer radical polymerization (eATRP) of styrene was studied in detail by using CuBr₂/TPMA (TPMA = tris(2-pyridylmethyl)amine) as a catalyst. Redox properties of various Cu(II) species were investigated in CH₃CN, dimethylformamide (DMF), and dimethyl sulfoxide (DMSO) both in the absence and presence of 50% (v/v) styrene. This investigation together with preliminary eATRP experiments at 80 °C indicated DMF as the best solvent. The effects of catalyst, monomer, and initiator concentrations were also examined. The livingness of the polymerization was studied by chain extension and electrochemical temporal control of polymerization. Full article

Abstract

Iron complexes are particularly interesting as catalyst systems over the other transition metals (including noble metals) due to iron’s high natural abundance and mediation in important biological processes, therefore making them non-toxic, cost-effective, and biocompatible. Both homogeneous and heterogeneous catalysis mediated by iron as a transition metal have found applications in many industries, including oxidation, C-C bond formation, hydrocarboxylation and dehydration, hydrogenation and reduction reactions of low molecular weight molecules. These processes provided substrates for industrial-scale use, e.g., switchable materials, sustainable and scalable energy storage technologies, drugs for the treatment of cancer, and high molecular weight polymer materials with a predetermined structure through controlled radical polymerization techniques. This review provides a detailed statement of the utilization of homogeneous and heterogeneous iron-based catalysts for the synthesis of both low and high molecular weight molecules with versatile use, focusing on receiving functional materials with high potential for industrial application.
