ABSTRACT:
The present invention comprises a water vapor permeable, pressure-sensitive adhesive composition useful for surgical and medical bandage applications, and incorporating modified copolymers of butyl acrylate containing N-vinyl 2-pyrrolidone and acrylic acid. The present pressure-sensitive adhesive composition results in enhanced water vapor transmission rates, which may lead to a concomittant reduction in skin lesions that were previously attendant upon the accumulation of water under conventional inadequately permeable pressure-sensitive adhesive-coated surgical and medical dressings.
