Conditions

Temperature: 85 °C

Procedure

This example demonstrates the effect of reaction temperature on the quat content. Example 9C was repeated except that the temperature was raised to 85° C. before the initiator was added. After 6 hours G.L.C. analysis showed no DMAEMA and no acrylamide present. This indicates that none of the DMAEMA had been quaternized.
