Cross-linked, hydrophilic pressure sensitive adhesive compositions, (meth)acrylate-functional polar polymers which serve as precursors to them, and medical products using such adhesives are disclosed. The cross-linked polymer is prepared by free-radically cross-linking reactive polymers that are functionalized with pendant polymerizable moieties. Medical products that include such compositions are biomedical electrodes, pharmaceutical delivery devices, and medical skin coverings such as wound dressings.

[ What is claimed is:] [1.] A hydrophilic pressure sensitive adhesive composition comprising:a crosslinked polar, hydrophilic polymer and sufficient humectant to render the composition pressure sensitive adhesive, wherein the crosslinked polymer is prepared from the reaction of hydrophilic, carboxy-functional polymers with epoxy-functional (meth)acrylates to become pendant polymerizable moieties, and wherein the hydrophilic, carboxy-functional polymers are functionalized with the pendant polymerizable moieties with an average of 2,500 to 25,000 g/mole molecular weight between the pendant polymerizable moieties along the backbone.
