ABSTRACT:
Pressure-sensitive acrylate-based adhesive copolymers comprising polymerized acrylate units and polymerized fluorochemical surfactant units and a process for preparing same. Also prepolymeric compositions comprising the monomeric components of an acrylate-based pressure-sensitive adhesive and a polymerizable fluorochemical surfactant. The prepolymeric compositions generally have surface energy lower than that of the monomeric components of the acrylate-based pressure sensitive adhesive alone. Also, the adhesive compositions better maintain adhesive properties when aged when compared to corresponding adhesive compositions involving non-polymerizable fluorochemical surfactants.
