Procedure

To a solution of 50.0 grams of acetic acid in 350 grams of water is added 131 grams of DMAEMA followed by 119 grams of acrylamide. The pH of the solution is 7.0 without any adjustment. The rest of the procedure is the same as followed in Example A. After 5 hours G.L.C. analysis showed there are no DMAEMA monomer remaining, while 33% of the acrylamide was recovered. This indicates that ≈ 66% of the DMAEMA had been quaternized.
