ABSTRACT:
This invention relates to pressure sensitive adhesive compositions which include an amine terminated polyalkylene oxide neutralized sulfonated thermoplastic polymer, wherein the neutralized sulfonated thermoplastic polymer has about 5 to about 250 meq. of neutralized sulfonate groups per 100 grams of the neutralized sulfonated thermoplastic polymer, dissolved in a nonreactive solvent at a concentration level of about 5 grams to about 25 grams per 100 ml. of nonreactive solvent. To control the end use properties of the solvent-based pressure-sensitive formulations, optionally, tackifying resins can also be incorporated in the solution.
