Abstract
Pressure sensitive adhesive (PSA) polymers, especially low T , high tack, nonpolar and polar polymers useful in formulating PSA can be solubilized or dispersed in a supercritical fluid (SCF), such as liquid CO or supercritical CO , using an organic cosolvent such as toluene. PSA polymers can be polymerized in SCF fluids to make unique adhesive products. Inclusion of a fluorinated reactant in the SCF polymerization process yields a PSA with improved resistance to mineral oil.
