ABSTRACT:
The present invention provides a water soluble vinyl monomer containing a vicinal diol group of the general formula: ##STR1## wherein R.sub.1 is hydrogen or methyl; R.sub.3 and R.sub.4 are independently methyl or ethyl; Y is oxygen or NH; X.sup.- is a halogen, sulfate, CH.sub.3 SO.sub.4.sup.- or C.sub.2 H.sub.3 SO.sub.4.sup.- or CH.sub.3 COO.sup.- and n is 2 or 3. Polymers containing the monomer when crosslinked in aqueous fluids form high viscosity gels which are stable at high temperatures and can be used in carrying out completion, stimulation, enhanced production and other treatments in subterranean formations.
