Summary: | 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. |
