Procedure

This example shows that phenyl acetate, when combined with an aldehyde, gels a polyacrylamide much slower than a phenol/formaldehyde organic crosslinking agent. A solution of Phillips HE-B® (5000 ppm), phenyl acetate (1500 ppm) and formaldehyde (1900 ppm) was prepared in synthetic sea water (pH unadjusted). This solution gelled after seven weeks of storage at 210° F.
