Procedure

This example demonstrates that phenyl benzoate, when combined with an aldehyde, gels a polyacrylamide much slower than would a phenol/aldehyde crosslinking agent. A solution of Phillips HE-B® (5000 ppm), phenyl benzoate (2000 ppm) and formaldehyde (1900 ppm) was prepared in synthetic sea water (pH unadjusted). This solution was observed to have gelled after nine weeks of storage at 210° F., versus overnight for the phenol/formaldehyde-crosslinked composition of Example 1.
