Special Issue Information

Dear Colleagues,

Polymer rheology is of great importance as there is a need to understand and/or control their viscoelastic properties for potential applications such as shaping for targeting processes. In parallel, it is pivotal to master their chemistry as it will have a direct impact on their rheological behavior.

This Special Issue, “Linking rheology and polymer chemistry”, covers the synthesis, characterization, and applications of polymers with a specific and systematic focus on their rheological behavior. We also kindly invite investigators to contribute original research that will deal with the monitoring of polymerization reactions on a rheometer, their crosslinking, or their chemical modifications (e.g., functionalization). Particular attention can be given to their chemical evolutions during reactions, or to their structures and properties, for example, by the means of coupling techniques with spectroscopy (IR, Raman, dielectric), microscopy, small-angle X-ray scattering, etc. Moreover, this Special Issue will welcome focused review articles that examine the state of the art, identify emerging trends, and suggest perspective directions for the rheological/chemical analysis of polymerization reactions.

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.

In the field of non-oxide ceramics, the polymer-derived ceramic (PDC) approach appears to be very promising, especially for obtaining easily shaped and homogeneous materials in terms of structure and composition. However, in order to reach a suitable form during the process, it is often necessary to study the rheology of preceramic polymers while they are modified during polymerisation or crosslinking reactions. Given this need in the understanding of the real-time rheology of macromolecules during their synthesis, a rheometer coupled with both an infrared spectrometer and a Raman probe is described as a powerful tool for monitoring in situ synthesised polycarbosilanes. Indeed, this original device allows one to control the viscosity of a hyberbranched polycarbosilane from defined difunctional and tetrafunctional monomers. Meanwhile, it links this evolution to structural modifications in the macromolecular structure (molar masses, dispersity and conformation), based on SEC-MALS analyses, synchronised by the monomer conversion determined by using Raman and infrared spectroscopies, a common denominator of the aforementioned instrumental platform.
