Progress in Polymer Science publishes state-of-the-art overview articles by internationally recognized authorities in polymer science and engineering, one of the fastest growing disciplines. The journal provides a link between original articles, innovations published in patents, and up-to-date knowledge of technology. It publishes review articles on subjects not only within the traditional fields of polymer science - chemistry, physics and engineering involving polymers - but also within interdisciplinary developing fields such as functional and specialty polymers, biomaterials, polymers and drug delivery, polymers in electronic applications, composites, conducting polymers, liquid crystalline materials and the interphases between polymers and ceramics, and new fabrication techniques, where significant contributions are being made. Contributors are usually invited by the Editor; however, authors wishing to submit a review to the journal may do so by first submitting a Proposal Form for consideration by the Editors. Upon submission, the proposal will be reviewed by the Editors for suitability and fit, and if appropriate, an invitation to submit the full paper will be extended. Proposal forms should be submitted via Editorial Manager, and authors should select "Proposal" as the article type. Unsolicited manuscripts submitted without a proposal form will not be considered.
