Procedure

As can be seen from the Table, after 7 hours g.l.c. shows only 3.5% residual DMAEMA but 35.7% acrylamide, indicating an approximate quat content of 35% (based on the DMAEMA in the copolymer). The percentage quaternization as determined by g.l.c. is generally in good agreement with the values obtained on similar systems by Nmr analysis.
