Abstract
Adhesive tapes (e.g., duct tapes) having a backing comprising a compatibilized release composition are reported. The compatibilized release composition comprises a thermoplastic olefin-based polymer comprising an acid or a base functionality and a polymeric release material comprising an acid or a base functionality. The functionality of the thermoplastic olefin-based polymer and the functionality of the polymeric release material provide an acid-base interaction that compatibilizes the release composition.
