Procedure

650 grams of calcium bromide hydrate (Aldrich, 98%) is added to 500 ml of DI water and allowed to dissolve. 100 ml of this solution is placed in an Erlenmeyer flask. 2.9565 grams (3.67 ml) of acrylonitrile (Aldrich, 99%), 1.9803 grams of acrylamide (Aldrich, 99%), 6.4702 grams (6.40 ml) of 2-hydroxyethyl acrylate (Aldrich, 96%), and 0.1498 grams (0.144 ml) of diethylene glycol diacrylate (Monomer-Polymer & Dajac Laboratories, Catalogue No. 7945) are added to the 100 ml of CaBr2 solution. Heat may be necessary to dissolve the acrylamide in the CaBr2 solution. The flask is sealed with a rubber stopper and N2 is bubbled through the solution for 30 minutes. In a 20 dram glass vial, 0.144 grams of VA-086 initiator is added to 10 ml of DI water and allowed to dissolve. Using a syringe, 5 ml of the VA-086 solution is added to the flask containing the reactants. The flask is swirled until well mixed and placed in an oven at 80° C. overnight to allow the gel to form.
