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.
Claims19
A release composition comprising a mixture of:
- a thermoplastic olefin-based polymer comprising an acid or a base functionality;
- from about 2% to about 10% by weight of the release composition at a polymeric release material comprising an acid or a base functionality;
- wherein the functionality of the thermoplastic olefin-based polymer and the functionality of the polymeric release material form an acid-base interaction;
- and
- wherein the thermoplastic olefin-based polymer and the polymeric release material form a compatibilized blend.
