[CH3:1][C:2]([C:4]([O:6][CH2:7][CH2:8][N:9]([CH3:11])[CH3:10])=[O:5])=[CH2:3].[C:12]([NH2:16])(=[O:15])[CH:13]=[CH2:14]>>[C:12]([NH2:16])(=[O:15])[CH:13]=[CH2:14].[CH3:3][C:2]([C:4]([O:6][CH2:7][CH2:8][N:9]([CH3:11])[CH3:10])=[O:5])=[CH2:1]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.
