ABSTRACT:
Acrylic pressure sensitive adhesives which exhibit hydrophilicity and moisture permeability can be made by curing or crosslinking low molecular weight acrylic oligomers modified with substantial quantities of a hydroxyl containing monomer. The resultant modified pressure sensitive adhesive acrylic copolymers, upon crosslinking, will then have a hydrophilic hydroxy component incorporated into the copolymer backbone. Such adhesives are particularly useful in skin contact applications, such as the adhesives used on bandages or the adhesives used in transdermal drug delivery systems.
