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.
Claims5
A pressure-sensitive adhesive composition comprising an amine terminated polyalkylene oxide neutralized sulfonated polymer dissolved in a nonreactive solvent system at a concentration level of about 5 to about 25 grams per 100 ml. of the nonreactive solvent system, wherein the amine terminated polyalkylene oxide of said amine terminated polyalkylene oxide neutralized sulfonated thermoplastic resin is an ethoxylated long-chain fatty acid derived amine having the formula:
- ##STR6## wherein x+y=5 to 200.
