PROBLEM TO BE SOLVED: To provide a pressure-sensitive pressure-sensitive adhesive polymer (PSA) useful for application to the skin in the field of transdermal drug delivery, for example, useful for application to the skin in the field of transdermal drug delivery. Pressure-sensitive adhesive polymer (PSA) is described. The PSA contains polar groups modeled on the basis of one or more polar moieties of skin lipids, which contribute to good skin adhesion. Methods of making the PSA, compositions containing PSA, and methods of making and using them are also provided. [Selection diagram] None |
