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.
