Polymers are nowadays a driving force in our society. Unfortunately, they have a major drawback: independent of the application, they experience changes in their macroscopic properties with time upon the impact of various external factors including temperature, radiation, humidity, and mechanical load. While many researchers conduct accelerated aging studies, the reported results rarely match the observations from the natural aging. The main raisons for this discrepancy are currently attributed to the spatial dependence of the changes with the aging time and the combined effects of various types of aging.
The macroscopic properties of polymers are largely determined by their morphology in terms of chemical structure, molecular dynamics, molecular weight, crystallinity degree etc. Thus, understanding and modeling the temporal and the spatial physical and chemical changes in the molecular network will provide the framework for establishing reliable structure-properties relationships requested for a better understanding of the experimental observations and for determining their lifetime. For this, one needs to take advantage of the capabilities of various modern analytical methods, which are able to probe different morphological aspects and to identify the most sensitive microscopic parameters towards aging. Moreover, there is great need for simple, robust, and low-cost analytical methods for onsite non-destructive morphological evaluation. In this way, systematic details about the microscopic changes associated with natural aging can be gained.
This special issue aims at collecting research and review articles covering all aspects of aging-induced morphological changes in polymer materials. It provides a platform for discussing challenges and open issues by presenting suitable morphological characterization techniques and modeling methods for improved structure-properties relationships.

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 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 2200 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.
