| 摘要 |
Hydrophilic, cohesive, pressure-sensitive adhesive compositions are provided comprising a) a crosslinked, swellable polymeric matrix made from an N-vinyl lactam monomer and a multi-ethylenically unsaturated compound, wherein the ethylenic groups are vinyl groups, allyl groups, and/or methallyl groups, which groups are bonded to nitrogen or oxygen atoms, and b) a plasticizer for the copolymer wherein the amount of the multi-ethylenically unsaturated compound and the plasticizer are present in amounts sufficient to render the polymeric matrix cohesive, swellable and pressure-sensitive adhesive. These compositions can also be used as adhesives for biomedical electrodes and transdermal drug delivery systems. |
