反応手順
To a solution of 40 grams of acetic acid in 350 grams of water is added 131 grams of DMAEMA followed by 119 grams of acrylamide. The pH is 7.7. The rest of the procedure is the same or that followed in Example A. After 5 hours g.l.c. analysis showed no DMAEMA present while 49.5% of the acrylamide was recovered which indicates that ≈99% of the DMAEMA had been quaternized. A small sample of the monomer solution was stored for 24 hours at 25° C. The NMR spectrum showed that 73% of the DMAEMA had been quaternized.
