Abstract
The invention relates to compatibilized release compositions useful in release layers of release articles (e.g., release liners) and adhesive articles (e.g., pressure sensitive adhesive tapes). The compatibilized release compositions comprise a mixture of 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 are selected to provide an acid-base interaction.
