Patent

CA 2509900

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.

L'invention concerne des compositions de décollage rendues compatibles utilisées dans des couches de décollage d'articles de décollage (par exemple, des doublures à décollage) et des articles adhésifs (par exemple, des bandes adhésives sensibles à la pression). Ces compositions de décollage rendues compatibles renferment un mélange d'un polymère à base d'oléfines thermoplastique contenant un acide ou une fonctionnalité basique. La fonctionnalité du polymère à base d'oléfines thermoplastique et la fonctionnalité de la matière de décollage polymère sont sélectionnées pour engendrer une interaction acide/basique.
