ABSTRACT:
This invention is directed to compositions useful as ionomeric hot melt pressure sensitive adhesive compositions. These compositions comprise a polymer containing carboxylic acid, a miscible metal salt, and an o-methoxy-substituted aryl acid. These compositions display low melt viscosity, simplifying application, as well as improved adhesive properties, especially shear resistance.
