    • The invention provides a pressure−sensitive adhesive for the skin excellent in pressure−sensitive adhesiveness to the human skin and repeelability therefrom, which does not cause the horny layer to be torn away in peeling and is lowly irritant to the skin; and tapes or sheets made by using the same. The pressure−sensitive adhesive is characterized by comprising (a) 100 parts by weight of a copolymer which is prepared from an olefinic macromonomer and a vinyl monomer and whose molecular weight (in terms of polystyrene and as determined by gel permeation chromatography (GPC)) has a two−peak distribution (with the proviso that when the copolymer is to be post−cured, the distribution is one as determined before the post cure) and (b) 20 to 250 parts by weight of a softener which is compatible with the copolymer and liquid or pasty at room temperature and has a boiling point of 250 °C or above (with the proviso that when the content of the softener (b) exceeds 80 parts by weight, the copolymer must be post−cured).

    • A method for preparing hydrophilic pressure sensitive adhesive (PSA) compositions is provided, wherein the method enables preparation of adhesives having a particular, optimized degree of adhesion. That is, the hydrophilic PSA is comprised of a hydrophilic polymer and a complementary short-chain plasticizing agent, wherein the hydrophilic polymer and plasticizing agent are capable of hydrogen bonding or electrostatic bonding to each other and are present in a ratio that optimizes key characteristics of the adhesive composition, such as adhesive strength, cohesive strength and hydrophilicy. The adhesive is useful in a wide variety of contexts, e.g., as a biomedical adhesive for application to the skin or other body surface, and as such finds utility in the areas of drug delivery systems (e.g., topical, transdermal, transmucosal, iontophoretic), medical skin coverings and wound healing products and biomedical electrodes.
