Special Issue Information

Dear Colleagues,

Step polymerization is the most common synthetic route used for the preparation of biodegradable and biobased polymers, allowing for a great variety of macromolecular structures and features. Several are the polymer families obtained via step polymerization, with polyesters, polyamides, and polyurethanes being probably the most significant examples, but also other polymers, such as polyethers, commonly synthesized using this approach.

Many challenges have to be faced by these kinds of polymers when dealing with biodegradation, especially when it is coupled with the need for tailored properties that the polymer should have depending on its application field.

For example, biodegradable polymers used in the packaging field should guarantee good mechanical properties for several months, even in harsh environmental conditions. On the other hand, when biomedical applications are targeted, degradation products should not be harmful for the body.

The need for such varied and demanding features makes research around these polymers extremely challenging and stimulating. Consequently, researchers are constantly studying complex macromolecular architectures, hybrid organic/inorganic systems and, more in general, innovative synthetic strategies and processing approaches.

The aim of this Special Issue is to highlight the progresses around step polymerization when it involves the synthesis of biodegradable and biobased polymers to be employed in a wide range of potential applications.

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. Polymers 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 1800 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.

Synthesis of Polylactic Acid Initiated through Biobased Antioxidants: Towards Intrinsically Active Food Packaging
Polymers 2020, 12(5), 1183; https://doi.org/10.3390/polym12051183 - 21 May 2020

Polylactide (PLA)-based polymers, functionalized with biobased antioxidants, were synthesized, to develop an intrinsically active, biobased and potentially biodegradable material for food packaging applications. To achieve this result, phenolic antioxidants were exploited as initiators in the ring opening polymerization of l-lactide. The molecular [...] Read more.
Polylactide (PLA)-based polymers, functionalized with biobased antioxidants, were synthesized, to develop an intrinsically active, biobased and potentially biodegradable material for food packaging applications. To achieve this result, phenolic antioxidants were exploited as initiators in the ring opening polymerization of l-lactide. The molecular weight, thermal properties and in vitro radical scavenging activity of the polymers obtained were compared with the ones of a PLA Natureworks 4043D, commonly used for flexible food packaging applications. The most promising synthesized polymer, bearing vanillyl alcohol as initiator (PLA-VA), was evaluated for active food packaging applications. Packaging with PLA-VA films reduced color and fat oxidation of salami during its shelf life. Full article
