Special Issue Information

Dear Colleagues,

This special issue is to honor Dr. Judit E. Puskas on the occasion of her 70th birthday and to celebrate her unique career, spanning more than a combined 40 years in industry and academe and her commitment to polymer science and engineering. Her research interest has always been in polymers for the betterment of humanity. Throughout her career she focused on several major topics, such as fundamentals of carbocationic polymerization, enzyme catalyzed polymer functionalization, understanding the biosynthesis of natural rubber and advanced implants and health care materials for women suffering from breast cancer. With her coworkers she pioneered controlled/living polymerizations, including carbocationic polymerizations in solution and emulsion, RAFT polymerization and Reversible Radical Recombination Polymerization (R3P). She is one of the co-inventors of the drug-eluting coating on the TAXUS coronary stent (Boston Scientific) that has been implanted into more than 10 million people since its FDA approval, generating more than five million dollars in license fees for the University of Akron. She was the first woman to receive the Charles Goodyear Gold Medal, the highest honor given by the Rubber Division of the American Chemical Society to scientist for their contribution to rubber science since 1941. She is Fellow of the American Institute of Medical and Biological Engineering (AIMBE), the International Union of Pure and Applied Chemistry (IUPAC), the National Academy of Inventors (NAI) and external member of the Hungarian Academy of Sciences.

As Guest Editors of Molecules, we would like to celebrate her career and contribution to polymer science by preparing this Special Issue collecting works related to recent advances in ionic polymerizations and related processes.

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 submissions that pass pre-check are 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. Molecules is an international peer-reviewed open access semimonthly 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 2700 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.

Photochemical techniques have recently been revitalized as they can readily be adapted to different polymerization modes to yield a wide range of complex macromolecular structures. However, the implementation of the photoinduced cationic methods in the polymerization of cyclic siloxane monomers has scarcely been investigated. Octamethylcyclotetrasiloxane (D4) is an important monomer for the synthesis of polydimethylsiloxane (PDMS) and its copolymers. In this study, the cationic ring-opening polymerization (ROP) of D4, initiated by diphenyl iodonium hexafluorophosphate (DPI), has been studied. Both direct and indirect initiating systems acting at broad wavelength using benzophenone and pyrene were investigated. In both systems, photochemically generated protonic acids and silylium cations are responsible for the polymerization. The kinetics of the polymerization are followed by viscosimetry and GPC analyses. The reported approach may overcome the problems associated with conventional methods and therefore represents industrial importance for the fabrication of polysiloxanes. Full article
