摘要：
A process is provided for preparing a pressure sensitive adhesive hydrogel, comprising: (A) providing an oligomeric precursor, the oligomeric precursor comprising a polyether moiety endcapped with ethylenic unsaturation, the oligomeric precursor being associated with methacrylic acid (B) providing an ethylenically unsaturated crosslinking agent selected from the group consisting of difunctional ethylenically unsaturated monomer, trifunctional ethylenically unsaturated monomer and combinations of the foregoing (C) free radically curing the oligomeric precursor and the ethylenically unsaturated crosslinking agent in water at a pH between about 3.5 and about 9 to provide the pressure sensitive adhesive hydrogel.
